Removed deprecated broken dxvk-async patch:
Upstream DXVK has implemented the GraphicsPipelineLibrary (GPL) back in August, which takes over dxvk-async's job:

doitsujin/dxvk#2798
Driver support for Nvidia was added in version 515.49.10:

Driver support for AMD/RADV was added in August 2022 and is an ongoing WIP:
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/17542
Per the above, it can be exposed/enabled for testing on AMD/RADV via:
RADV_PERFTEST=gpl
dxvk-async now causes problems with the dxvk-cache, which is not something new users may know how to clear:
Sporif/dxvk-async#55
In light of the above, in addition to the current rebase still not working properly, I am removing the dxvk-async patch from Proton-GE.
RIP dxvk-async 2018-2023
