debug_utils: Minor individual interface changes

PL:U Added SharedFonts loading via TTF

hid: Move core include to cpp file

core: Remove always true conditionals in Load()

set: Fixed GetAvailableLanguageCodes() to follow the max_entries

Rightnow, in games use GetAvailableLanguageCodes(), there is a WriteBuffer() with size larger than the buffer_size. (Core Critical core\hle\kernel\hle_ipc.cpp:WriteBuffer:296: size (0000000000000088) is greater than buffer_size (0000000000000078))

0x88 = 17(languages) * 8
0x78 = 15(languages) * 8

GetAvailableLanguageCodes() can only support 15 languages.
After firmware 4.0.0 there are 17 supported language instead of 15, to enable this GetAvailableLanguageCodes2() need to be used.
So GetAvailableLanguageCodes() will be caped at 15 languages.

maxwell3d: Move FinishedPrimitiveBatch event after AcceleratedDrawBatch()

gl_rasterizer: Correct assertion condition in SyncLogicOpState()

filesystem: Fix typo in log message

file_sys: Add support for NAX archives

Quite a bit of these aren't necessary directly within the debug_utils
header and can be removed or included where actually necessary.

Avoids implicit conversions.

Ensures that all class members are initialized.

The start and finish events should likely not be right after one another
like this, otherwise the batch will appear to complete immediately

qt: Add filename and title id to window title while running

These conditions are always true, since the outer conditional already
checks for these conditions.

This isn't required to be in the header. Instead, directly include what
this header needs and move it to the cpp file where it belongs.

Previously the assert would always be hit, since it was the equivalent
of: array == nullptr, which is never true.

Shaders: Added decodings for IADD3 instructions

* Port #4013 from Citra: "Init logging sooner so we dont miss some logs on startup"

* Fix compilation

This is needed because the title IDs of update NCAs will not use the update title ID. The only sure way to tell is to look for a partition with BKTR crypto.

* Added GetBootMode

Used by homebrew

* Added enum for GetBootMode

gl_rasterizer_cache: Several improvements

gl_rasterizer: Implement partial color clear, stencil clear, and stencil test.

On call to WriteKeyToFile, so that the autogenerated file can be written.

Stored in a separate file than manual keys.

Should make key gets marginally faster.

Returns the file before calling parser on it.
