this is just the program-based handling, which means finding the right
variant and/or creating new ones based on matching a 32bit mask indicating
which textures must be rewritten

this reduces the component key size for decomposition by up to 75%, down
to as low as 2 bytes, which is more optimal for both hashing and memcmp of
the key
it will become more useful as further changes are added to improve vertex format
support, enabling the keysize to remain relatively small

We can't do any of this logic if key is NULL, because that means we'll
dereference memory close to a NULL-pointer.
While we're at it, add some asserts to the zink_fs_key and zink_vs_key
functions who would otherwise be responsible for giving us invalid
non-null pointers out of null-pointers.

now that there exists a shader key for vertex stages, we can stop modifying
the zink_shader values and instead use this as a more reliable method of detecting
the state

GL allows the pipeline to "infer" a tcs shader if a tes shader is bound using
API-specified default values for gl_TessLevelOuter and gl_TessLevelInner,
but VK requires that both shaders be explicitly present
to handle this, create a generic tcs which translates all vs outputs to
invocation-based arrays and copy the appropriate value to the expected tes
input array location. also emit the default inner/outer values as push constants
so we don't have to recompile the shaders whenever the api calls occur
