[Coretiming/NVNFlinger] Improve multi-core vsync timing, and core timing accuracy

audio_core: Mark several member functions as const

GIT: Modify .gitignore to ignore wildcard for build directories

UI: move icons from default into colorful theme.

Helps if you have multiple build folders. There are other, dark ways to
hide extra build folders from git, but this is better.

See: https://github.com/citra-emu/citra/pull/6130

core/CMakeLists.txt: Remove duplicate files.

common: Use PROJECT_SOURCE_DIR to find CMakeModules

yuzu qt: Add option to create Windows crash dumps

ci,linux: Support Patreon releases

audio_device: Make AudioDeviceName constructor constexpr

This is just being copied and isn't modified at all.

These two don't modify member state.

This doesn't modify member state.

We can also mark the parameter of AppendError as const as well, since it
isn't modified.

This doesn't modify instance state.

These functions don't modify class state, so we can mark them as such

These don't affect class state, so we can mark them as such.

This function doesn't modify the passed in buffer, so we can make that
explicit.

Simplifies the indexing code a little bit.

These functions don't modify the passed in audio buffers, so we can
signify that in the interface.

colorful theme has been default theme for awhile. having colorful theme
try and grab icons from other theme doesn't work on Linux.

Also adding two additional icons, info is to hint to the user that they
should hit verify after pasting in a token, sync is to show that the
verification is occurring.

Remove pause callbacks from coretiming

qt_themes: Update sd card icon

audio_core: Amend documentation comment tags

UI: Fix link to TAS help page

Resolves a wackload of -Wdocumentation warnings due to mismatching tags
and whatnot.

common: do not link to xbyak on non-amd64 architectures

These member functions don't modify any internal state.

These are used as read-only arrays, so we can make the data read-only
and available at compile-time.

Now constructing an AudioDevice no longer needs to initialize some
tables

Tools -> TAS -> Configure TAS

Thanks to Rei on discord for the fix.

Basically: openExternalLinks is a checkbox in Qt Creator

compressor: Remove unneeded casts in ApplyCompressorEffect 

Provides equivalent behavior while being significantly smaller.

These functions don't modify the parameters.

Same behavior, but also silences a -Wcast-qual warning, since the second
cast casts away const.

input_common: Increase mapping timer from 2.5 seconds to 4 seconds
