This should stop AchievementManager::LoadGame from being called for the
default ISO when CBoot::BootUp is booting something other than a disc or
IPL (most notably, the Wii Menu), while still detecting all disc changes
that happen while a disc game is running.
Don't copy null terminators from the log's `header.gameid` into
`FifoDataFile`'s `m_game_id`.
Doing so would cause an infinite loop in `Core::GenerateScreenshotName`
as the various concatenations and `fmt::format` calls would then
effectively drop all the timestamps and disambiguating arbitrary numbers
since they followed the null terminator in the gameid, and so the
`File::Exists` calls would always return true.

In some Triforce games (e.g. _F-Zero AX_), the bytes that follow the
region flag in the `boot.id` file (at `0x38`) happen to be `0x00`.
However, in other games (e.g _Mario Kart Arcade GP 2_), it seems the
region flag is padded with `0xFF`.
_Mario Kart Arcade GP 2_ (`boot.id` in the USA version):
```
00000 0000: 42 54 49 44 00 00 01 E0 00 00 00 01 00 00 00 01 BTID.... ........
00000 0010: FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF ........ ........
00000 0020: 47 43 41 4D 00 00 01 C0 07 D3 05 0F 00 00 00 07 GCAM.... ........

region flag
```
When the region flag was tested in `switch` statements (where a single
byte was expected in the `case`s), the test would fail, depending
on the game.
This issue would lead to the wrong calculation of the country in
`VolumeDisc::GetCountry()`, which was then used to build the game ID in
`VolumeDisc::GetGameID()`.
The solution is to test using only the least meaningful byte in the
region flag.
Unexpected game IDs were first noticed with USA version of _Mario Kart
Arcade GP 2_, which was wrongly assigned the same game ID that is given
to the Japan version (i.e. `GNLJ82`). The correct game ID for the USA
version is `GNLE82`.
Check the return value of calls to `GetBuffer` and stop the `WASAPI
handler` sound thread if they fail.
This prevents a crash due to a null pointer dereference if `GetBuffer`
is unable to retrieve a buffer, which could be triggered during
emulation by disabling the selected WASAPI output device in the Windows
Sound settings.
Reasons:
- Only 0.000341% of all Android users were on API 21-23 in the last 365 days.
- These devices are old and likely do not run Dolphin well.
- Android 5.x and 6.0 have been without security updates for about 8 years.
- Staying on API 21–23 blocks AndroidX updates, including Lifecycle.
