* Fix for https://github.com/Arisotura/melonDS/issues/1169
LoadNAND was storing the stage 2 bootloader, while NWRAM access was disabled by Bit25 of SCFG_EXT putting the stage 2 into old shared WRAM, while executing it later with the bit enabled and fetching from an empty NWRAM.
* Fixed bug, where access to the NWRAM Bank A used the wrong page mask for write access
* Remove spaces before comma

* SCFG_BIOS now selects between NDS and DSi BIOS
Allowing experimental direct boot.
* - making NWRAM Priorities work as in the HW
- fixed loading DSi stage2 Bootloader when in direct boot (should not be loaded) and might interfere with the image loaded into the (N)WRAM previously
* NWRAM and SCFG Registers are now write-guarded by the corresponding SCFG_EXT7/9 Bits
* removed debugging remainder
* Moved NDSHeader dependent SCFG initialization into the new DSi::SetupDirectBoot function called from NDS::SetupDirectBoot when ConsoleType is DSi
* removed redundant SCFG_BIOS bit checks
* Set of changes from RSDuck's review
* removed a forgotten comment
* - removed the guarded debug outputs for NWRAM
- NWRAM writes to bank and window registers now apply their write masks.
- added comment on an existing TODO within the code describing, why this is OK
- fixed initial NWRAM bank reset just accessing set A
* NWRAM not mapped to 03... range if bit25 in SCFG_EXT is cleared
* removed NWRAM write block on cleared bit25 in SCFG_EXT
* changed type of iterator for MapNWRAM_x functions from s8 to int
* - reduced calculations/comparisons on NWRAM write operations
- changed u8 to unsigned int for an iterator MapNWRAM_x

* - added fallback to DSi footer copy at 000FF800h if reading footer at end of file failed. See https://problemkaputt.de/gbatek.htm#dsisdmmcimages
- changed output of ConsoleID to use PRIx64 to be consistent with all other tools working with the consoleID (readability/cosmetic improvement)
* Remove extra space

* Add PoroCYon's DSP code.
* Remove some teakra iles that we dont need.
* make some requested changes.
* move DataMemoryOffset into namespace.
* use deault param.
* ad the switch change
* <Generic> forget about the default parameter
* Implement NO$GBA debug registers.
NO$GBA comes with 4 debug registers that allow a ROM to print text to
the emulator terminal and 2 other status registers, one with the name of the
emulator and the other with the clock cycles count. This commit
implements them for the ARMv5 processor.
Some small things to note:
- `NocashPrint` was changed and now it takes an address to _the string_ instead of the flags before it (those
don't do anything anyways).
- The "Emulation ID" register contains the string "melonDS " followed by version, _not_ "NO$GBA"
* Fix styling issue and improve comment regarding NO$GBA message flags
