audio_core/filter: Add explicit cast to assignment in Process()

shader_bytecode: Parenthesize conditional expression within GetTextureType()

Resolves a -Wlogical-op-parentheses warning.

Previously this would cause warnings about implicit conversions to s16
from a double

sdmc_factory: Remove unnecessary core include

bit_field: Convert ToBool() into explicit operator bool

Port #4056 from Citra: "Add Clear Recent Files menu action"

perf_stats: Change MAX_LAG_TIME_US to an appropriate value

25us is far too small, and would result in std::this_thread::sleep_for
being called with this as a maximum value. This means that a guest
application that produces frames instantly would only be limited to
40 kHz.

25ms is a more appropriate value, as it allows for a 60 Hz refresh
rate while providing enough slack in the negative region.

This doesn't require the central core header to be included, it just
needs the vfs headers.

Gets rid of a TODO that is long overdue.

rasterizer_interface: Remove renderer-specific ScreenInfo type from AccelerateDraw() in RasterizerInterface

romfs_factory, service/filesystem: Use forward declarations where applicable

Shaders: Implement depth writing in fragment shaders.

renderer_opengl: Use LOG_DEBUG for GL_DEBUG_SEVERITY_NOTIFICATION and GL_DEBUG_SEVERITY_LOW logs

Rasterizer: Use PBOs to reinterpret texture formats when games re-use the same memory.

LOG_TRACE is only enabled on debug builds which can be quite slow when
trying to debug graphics issues. Instead we can log the messages to the
debug log, which is available on both release and debug builds.

gl_stream_buffer: Add missing header guard

Avoids the need to rebuild multiple source files if the filesystem code
headers change.

This also gets rid of a few instances of indirect inclusions being
relied upon

Prevents potential compilation errors from occuring due to multiple
inclusions

We'll write <last color output reg + 2> to gl_FragDepth.

telemetry_session: Don't allocate std::string instances for program lifetime in GetTelemetryId() and RegenerateTelemetryId()

gl_shader_decompiler: Implement TextureCube/Texture3D for TEX/TEXS.

Shaders: Write all the enabled color outputs when a fragment shader exits.

Shaders: Fixed texture coordinates in TEX with Texture2D

The X and Y coordinates should be in gpr8 and gpr8+1, respectively.

This fixes the cutscene rendering in Sonic Mania.

acc/profile_manager: General cleanup

externals: Update dynarmic to a42f301c.

Avoids the need to rebuild whatever includes the romfs factory header if
the loader header ever changes. We also don't need to include the main
core header. We can instead include the headers we specifically need.

filesystem: Add support for loading of system archives

Revert "Port #3616 from Citra: "appveyor: set jobs to 4 for mingw""

telemetry_session: Don't allocate std::string instances for program lifetime in GetTelemetryId() and RegenerateTelemetryId()

Given these functions aren't intended to be used frequently, there's no
need to keep the std::string instances allocated for the whole lifetime
of the program. It's just a waste of memory.

This is only used in a shared_ptr, so we can forward declare it.
