JosJuice c0eb95481f VolumeVerifier: Align partition reads to groups
This improves the speed of verifying Wii WIA/RVZ files.
For me, the verification speed for LZMA2-compressed files
has gone from 11-12 MiB/s to 13-14 MiB/s.

One thing VolumeVerifier does to achieve parallelism is to
compute hashes for one chunk of data while reading the next
chunk of data. In master, when reading data from a Wii
partition, each such chunk is 32 KiB. This is normally fine,
but with WIA and RVZ it leads to rather lopsided read times
(without the compute times being lopsided): The first 32 KiB
of each 2 MiB takes a long time to read, and the remaining
part of the 2 MiB can be read nearly instantly. (The WIA/RVZ
code has to read the entire 2 MiB in order to compute hashes
which appear at the beginning of the 2 MiB, and then caches
the result afterwards.) This leads to us at times not doing
much reading and at other times not doing much computation.
To improve this, this change makes us use 2 MiB chunks
instead of 32 KiB chunks when reading from Wii partitions.

(block = 32 KiB, group = 2 MiB)

JosJuice 10e1acf25c VolumeVerifier: Handle overlapping blocks more efficiently
The performance gains of doing this aren't too important since you
normally wouldn't run into any disc image that has overlapping blocks
(which by extension means overlapping partitions), but this change also
lets us get rid of things like VolumeVerifier's mutex that used to
exist just for the sake of handling overlapping blocks.

JosJuice 7ef0bc0359 VolumeVerifier: Split TMD error from ticket error for WADs
When I first made VolumeVerifier, I figured that the distinction
between an unsigned ticket and an unsigned TMD was a technical
detail that users would have no reason to care about. However,
while this might be true for discs, it isn't equally true for
WADs, due to the widespread practice of fakesigning tickets to
set the console ID to 0. This practice does not require
fakesigning the TMD (though apparently people do it anyway,
at least sometimes...), and the presence of a correctly signed
TMD is a useful indicator that the contents have not been
tampered with, even if the ticket isn't correctly signed.

JosJuice 829f3cff6f VolumeVerifier: Ignore invalid partitions in GetBiggestReferencedOffset
Otherwise GetBiggestReferencedOffset might treat garbage data as a valid
large offset, making Dolphin incorrectly say that the disc is too small.

JosJuice 56d37d773b RedumpVerifier: Show an error when datfile lacks serials or versions
This happens if someone manually downloads a regular datfile from
redump.org and puts it where Dolphin stores datfiles. Dolphin needs
"special" datfiles that contain fields for serials and versions.

Before this change, all discs (except Datel discs) would show up as
"Unknown disc" when using a regular datfile.

JosJuice 4b73d18eaa Re-implement FixCommonKeyIndex for WAD files
The old implementation of this was not able to distinguish between
a title that had the common key index set to 1 because it actually
was Korean and a title that had the common key index set to 1 due to
fakesigning. This new implementation solves the problem by
decrypting a content with each possible common key and checking
which result matches the provided SHA-1 hash.

The problem that the old implementation causes has only been reported
to affect a certain pirated WAD of Chronos Twins DX (WC6EUP), but it's
possible that the problem would start affecting more WADs if we add
support for the vWii common key (which uses index 2). Adding support
for the vWii common key would also prevent us from using the simpler
solution of always forcing the index to 0 if the title is not Korean.

Lioncash d220e33862 DiscIO/VolumeVerifier: Make no-argument overload of GetBiggestUsedOffset() const
The overload taking a partition is already a const member function, so
this one can be turned into one as well.

Lioncash fa57396e97 DiscIO/VolumeVerifier: In-class initialize members where applicable
Removes redundant initializers from the constructor and provides
initializers for all members that don't already have one for consistency
(and deterministic initial state).

Lioncash 52eb2d0d82 DiscIO/VolumeVerifier: Default destructor within the cpp file
Given the volume verifier has quite a few non-trivial object within it,
it's best to default the destructor within the cpp file to prevent
inlining complex destruction logic elsewhere, while also making it nicer
if a forward-declared type is ever used in a member variable.

Lioncash 0ccaa2b5d6 DiscIO/VolumeVerifier: Take std::string by value in AddProblem()
This allows both std::moving into the function and moving the parameter
from within the function, potentially avoiding an unnecessary copy.
