now that zink_gfx_lib_cache::stages_present exists (and is correct),
this value can be used directly to effect cache eviction instead of depending
on the prog->stages_present value, which may not even be the same prog that
owns a given zink_gfx_lib_cache instance
this fixes the case where a shader used in multiple progs with differing shader
masks would never have all its gpl pipelines freed
fixes leaks with caselist:
KHR-Single-GL46.arrays_of_arrays_gl.InteractionUniformBuffers1
KHR-Single-GL46.subgroups.quad.framebuffer.subgroupquadbroadcast_3_float_vertex
Fixes: d786f52f1f ("zink: prevent crash when freeing")
