gallium: Add cap to request state validation for all dirty state

With aaa4b0e6 state validation is no longer called for all changed states,
but only for states that will be active with a new shader program.
Not all drivers support this and might prefer if the state validation
is emitted for all states that might be changed. So add a cap that the
driver can signal one or the other preference, and default to the new
behavior.

Fixes: aaa4b0e6
   st/mesa: move check_program_state code into _mesa_update_state

v2: - Rename cap and and invert its meaning, query the cap
      only once and store it in st, handle the mask update
      when updating the shader i.e. not in st_validate_state (Marek)
