Tightens the data flow between the CPU and UI threads
to resolve multiple race conditions, such as:
1. Unbinding a debug interface update CB while it's in use,
causing a possible use-after-free.
2. Binding breakpoints via the disassembly widget that would read
a stale local variable, and bind the breakpoint to a bogus address
+ probably more subtle races that are now resolved
Adds memory search comparisons for Increased, Increased By, Decreased, Decreased By, Changed, Not Changed, Changed By.
For arrays, adds not equals, changed, not changed for filter searches.
Now only shows the comparison types that are currently valid for the given search type and if there's prior search results.
Also refactors to allow holding the prior set of search results rather than just the addresses, needed for these search comparisons to work.
Also adds a ui label to show that the debugger is searching after clicking the search button which then gets replaced with the results count when the search completes.
The debugger now refreshes/updates it's widgets once a second so that the user does not need to interact with the debugger to know when data/state changes.
Moves the Memory Search fucntionality to it's own widget so as to not pollute the CpuWidget with search related functionality, especially as it is intended to grow in scope. CpuWidget is fairly general and as such everything tends to get tossed together which makes it harder to navigate/understand/maintain.
Adds `/inis/debuggersettings/` settings folder to contain settings specifically for the debugger. Adds functionality to manually save (to settings) Breakpoints/Saved addresses and automatically load them upon launching the debugger.
Adds const to variables that could use them but currently don't and replaces 256 literal uses with Qt::UserRole to be clear what it is for and how this number is used as currently it's a bit confusing.
Previously when double clicking a memory search result it would go to the address but not switch to the memory view tab if the user wasn't already on it.
Now it ensures the user moves to the memory view widget, as this is almost always going to be the user's intention.
Adds a tab widget to the debugger that allows saving/bookmarking memory addresses and giving them labels/descriptions for convenience. Includes the ability to jump back to memory addresses from the Saved Addresses tab, and adding Saved Addresses from memory search search results context menu and the memory view context menu.
Also supports importing and exporting the saved addresses as CSV format.
Adds the ability to do Not Equals filter searches for arrays and strings. Refactors array search function for easily adding new search types.
Adds error message that informs the user that Not Equals can not be used for initial searches and can only be used for filter searches.
* Debugger: Fix Importing Breakpoints CSV functionality
This resolves a few issues with the Breakpoint CSV importing functionality.
Makes the following changes/fixes:
- Assembly instructions with commas caused part of the instruction text to be considered the start of a new column (comma is the CSV delimiter), resulting in "too many columns errors" and failing to import. Now puts values in quotes and detects the true start and end of the values, so that no extra columns are created.
- The import function was using the incorrect columns to load since the Enabled column was moved to be the first one but the import function had not been updated. Fixed this by using the column enum values instead of hardcoded numbers, so if ordering in the model changes it will still import fine.
- Updates the beginRemoveRows function to not remove an extra row. With this function you would want a "count" of 0 to remove 1, so "row, row" deletes one, "row, row+1" deletes 2. Updates it to subtract one so that the range is not including one more than it is intended to.

* Misc: Cleanup regex string & add explicit imports
Uses raw string literal to make the regular expression easier to read since regex is ugly enough as it is, we really don't need escaping characters in a string on top.
Also explicitly includes used Qt classes.
* Make memory search search type handling more clear with enum
Adds an enum class to represent the Search type used in a memory search. Prior, this was just handled with an integer to represent each type, but it was very unclear what corresponded to which type at first glance.
Made this easier to follow by using an enum to represent the type.
* Debugger : Add support for greater than/less than/not equal search types
Adds support for basic greater than/greater than or equal/less than/less than or equal/not equal search types for the debugger's Memory Scan.
This adds a new input to allow selecting the search comparison type, which defaults to Equals, and allows switching to the above mentioned comparisons.
It's set up to allow for adding more easily. Restructures some of the functions to make having multiple comparisons quite manageable.
Adds an enum for search comparison types for easy logic handling.
* Debugger: Update Array/String search type error to mention not handling Not Equals
Currently array/string searches don't support Not Equals searches, so this needs to be removed.
* Debugger: Code cleanup + feedback changes
Sets up if expressions to use constexpr for compile time evaluation and makes the is greater/less than logic simpler to read for int. Also removes an unneeded QPushButton cast and simply compares the pointers directly.
Adds the ability to remove individual search results from the Memory Search results list. Right clicking a result will give the "Remove Result" option in the context menu.
Allows user to right click a memory search result in order to go to that memory address location in the disassembly view. This saves several step and makes it easier to do.
Also adds precedent for the memory search result context menu which will be used in future features.
Consistent with the other models, and saves some awkward usage in the cpu widget where we have to interpret the variant as a string, to then convert it to a uint. I like this better as it provides an easy interface to get the 'raw' breakpoint data out of the model.
