service: spl: Implement general SPL service

service: time: Use GetFileRelative to get files within subdirectories

vk_master_semaphore: Use jthread for debug thread

ci: windows: Copy the Qt styles directory when packaging

core: Make is_powered_on atomic

Fixes potential data races when shutting down.

kernel: Fix missing peak set in KResourceLimit::SetLimitValue

Update dynarmic and add new unsafe CPU option.

nvflinger: Add experimental toggle to disable buffer swap interval limits

externals: httplib: replace custom httplib header with upstream as submodule

Qt can make use of qwindowsvistastyle.dll if present, and our MinGW
container has the library, but it was not being copied during the
packaging process. Thus, yuzu looked like a Windows 98 application when
using the PR-verify artifacts.

This copies over the DLL during packaging, for that sweet-sweet Windows
Vista style.

In addition, set the Qt plugins path instead of the plugins/platforms
path. This way we can use the directory directly, rather than appending
a `..` everytime we need something just outside of it.

host_memory: Correct MEM_RESERVE_PLACEHOLDER

Microsoft defines `MEM_RESERVE_PLACEHOLDER` as `0x00040000`, but our
manually imported version of it drops the last zero.

This also includes a minor change to web_service.cpp - to fix compatibility with upstream changes.

update submodule discord-rpc to latest [now deprecated]

The timezone info file can be within subdirectories (such as Asia/Tokyo), use GetFileRelative instead of GetFile to get files within subdirectories.

vulkan_debug_callback: Skip logging known false-positive validation errors

Avoids overwhelming the log with validation errors that are not applicable

Enabling this setting will allow some titles to present more frames to
the screen as they become available in the nvflinger buffer queue.

Audio: SDL2 audio backend

texture_cache/util: Avoid relaxed image views on different bytes per block

textures: Add a toggle for GPU Accelerated ASTC decoder 

fsp_srv: Fix filesystem access logging

The Append open mode will create a new file if said file does not exist at a given path, making this call redundant.

This introduces a new setting Enable FS Access Log which saves the filesystem access log to sdmc:/FsAccessLog.txt

If this setting is not enabled, this will indicate to FS to not call OutputAccessLogToSdCard.

Fixes softlocks during loading in Xenoblade Chronicles 2 when certain DLC is enabled.

common: fs: file: Flush the file to the disk when Flush() is called

Per the spec, L1 is clamped to the value 0xff if it is greater than 0xff. An oversight caused us to take the maximum of L1 and 0xff, rather than the minimum.

Huge thanks to wwylele for finding this.
