mesa/st: Extend st_context_invalidate_state with meta-op flags

Browse source 
Add ST_INVALIDATE_* flags for all states that meta-operations
(bitmap, clear, drawpixels, etc.) modify behind the state tracker's
back. This enables meta-ops to use st_context_invalidate_state()
instead of CSO save/restore for state re-derivation.

The atoms already know how to re-derive Gallium state from GL context,
so marking states dirty via st_context_invalidate_state() is
sufficient - st_validate_state() will call the atoms before the next
draw.
