codecs: Implement VP8 video decoding support

shader: Spirv support legacy attribute v2

ci: Print traceback on patch merge failure

Logging: Impl refactor

These functions were composing the entire frame, not just the headers. Rename to more accurately describe them.

Enables frame decoding with FFmpeg

program_metadata: Add default ThreadInfo capability

applets/swkbd: Skip text checking if the text has been confirmed

The text check message can be encoded in UTF-8.

Confirm means that the text has already been checked by the application to be correct, but is asking the user for confirmation.
The confirmation text itself seems to be corrupted though, this needs to be investigated.

service: acc: Stub acc:u0 '160'

- Used by Animal Crossing: New Horizons v2.0.0

Since the name is currently unknown, '160' is used as a placeholder.

svc: Correct WaitSynchronization num_handles param type

num_handles is a s32

ShaderCache: Order Phi Arguments from farthest away to nearest.

gl_rasterizer: Remove unused includes

common, result: Implement a subset of std::expected and use it in ResultVal

This is made obsolete by the presence of implicit constructors.

This amends the documentation slightly to reflect the updated interface.

Common::Expected effectively provides the same functions as ResultVal, so we can implement it with this.
This can be replaced with std::expected with minimal effort should it be standardized in the C++ Standard Template Library.
