This implements the use of VK_FILTER_CUBIC_EXT as a replacement for the software-based bicubic window adapting filter, used primarily for texture sampling in upscaled or downscaled surfaces such as UI, transparency effects, and screen-space elements in Unreal Engine 4 titles.
The Vulkan cubic filter is now conditionally enabled if the following are satisfied:
The device supports VK_EXT_filter_cubic
The format used supports VK_FORMAT_FEATURE_SAMPLED_IMAGE_FILTER_CUBIC_BIT_EXT
This change improves visual quality while reducing GPU workload by offloading cubic filtering to the driver instead of running custom sampling code in shaders. On supported hardware (e.g. desktop GPUs or high-end Adreno/AMD devices), it results in smoother transitions, improved transparency sampling, and better fidelity with lower shader complexity.
Fallback to the original software bicubic logic remains in place for devices lacking the extension or format capability.
Tested on several UE4 titles and confirmed to preserve or enhance visual output, especially in alpha-blended and UI-heavy scenes.

This commit adds a working implementation of the `GetBufferHistory` transaction in `BufferQueueProducer`, removing the previous stub.
Adapted by Jarrod Norwell for Sudachi, this implementation references the behavior in Ryujinx; commit rescued by Maufeat and another Eden teammate from Sudachi's reference, fixed and adapted for Eden usage.
It helps improve compatibility with Unreal Engine 4 titles and others that depend on proper surface history tracking for rendering pipelines, especially with regard to lighting, bloom, and alpha transitions.
Functionality has been tested for stability and does not introduce regressions, though further validation is recommended.

This commit introduces an implementation for `ZBCSetTable` in `nvhost_ctrl_gpu`, which is invoked by games and system services to configure default clear values for depth, stencil, and color attachments on the GPU, allowing better instructions on how the ZCull Block Compression expects to work within the emulated GPU.
This is an important step for compatibility with titles or system modules that expect ZBC configuration support.

FreeBSD doesn't support NVDEC, CUDA, and partially supports VAAPI (mostly for firefox).
Implementing VAAPI for other use cases would be a little bit complicated so, I chose to switch it off for FreeBSD.
This PR ensures that FFmpeg will always default to software decoding on FreeBSD, but should remain the same functionalities for other OS's.
The results are slight CPU increases while decoding in software mode, but still neglectable and they don't really harm performance.

Previously, if the user selected a per-game driver and that driver was
deleted from the global menu, it would cause a crash, it was because of
a mismatch between FileNotFoundException and NoSuchFileException. To
avoid the inconsistency I just made the check for if a file exists or
not to be separate.

Adds a menu option to install firmware from a packed ZIP.
This PR additionally lays the groundwork to add data import/export via ZIP. In the future, a qt_common subproject should be added to handle common Qt tasks such as this.
Furthermore, to decrease dependency complexity, this also introduces CPM, a wrapper around FetchContent. In theory, this should also lay the groundwork for #8 as well.

Extracts some firmware version/verification functions into
`frontend_common` to reduce duplicate code, especially for the new QML
frontend.
Additionally adds a check for games that are known to require firmware
(e.g. MK8DX) and warns the user if they don't have firmware installed
and attempt to run the game.
Firmware installation is to be in a separate PR.
