shader cache: Fix invalid virtual address clean up (#1717)

* shader cache: Fix invalid virtual address clean up

This fix an issue causing the virtual address of texture descriptors to
not be cleaned up when caching and instead cleaning texture format and swizzle.

This should fix duplicate high duplication in the cache for certain
games and possible texture corruption issues.

**THIS WILL INVALIDATE ALL SHADER CACHE LEVELS CONSIDERING THE NATURE OF THE ISSUE**
