nir/print: bit of state refactoring

Rename print_var_state to print_state, and stuff FILE ptr into the state
object.  This avoids passing around an extra parameter everywhere.

v2: even more extensive conversion.. use state *everywhere* instead of
FILE ptr, and convert nir_print_instr() to use state as well
