I confirm it makes the shader loading a lot faster (tested on Linux). Congratulations ! |

Description
This adds caching of SPIR-V and metadata to the slang shader backend, which significantly reduces shader compile times on large presets like the Mega Bezel shaders.
I didn't add an option in the menu for this, since it seems like a thing that's generally a good idea, but it could be done.
Related Issues
Couldn't find any, but people commonly complain about the long stalls, especially when loading new games or toggling fullscreen on/off

@warmenhoven would you be able to try/test this on Apple gear?
