meson: Make shader-cache a trillean instead of boolean
So that it can be implicitly disabled on windows, where it doesn't
compile.
v2: - Use an auto-option rather than automagic.
- fix shader_cache check (== -> !=)
v4: - Use new with_shader_cache instead of get_option('shader-cache')
elsewhere in the meson build
