      We sort of hackily recreate the concept of a program cache containing a
cache for multiple shaders, because of the way the `pl_pass` program
cache works.

In theory this is somewhat redundant with the existing concept of e.g. a
VkShaderModule, but we do things this way because it allows us to also
save other resources related to programs, for example the cached SPIR-V
(and also allows us to work with APIs that only cache programs on a
per-program basis)

We also expose this to the `pl_renderer` API.
