[shader_recompiler] fix META_TABLE/NUM_ARGS table being duplicated per TU that included opcodes.h (#4180)

small oopsie; we dont need 6 copies of the same 22KB table
(removes 5*22 = 110 KB worth of redundant stuff)

this also enforces static on the types defined in the header so they arent memoized into a non-inlined value (aka. compiler just grabs value instead of well, yknow, assuming its a constant area)
