dri: Introduce SWAP_METHOD tokens

We shouldn't be using GLX tokens in the dri subsystem, so define dri
SWAP_METHOD tokens and translate when necessary. Unfortunately the X server
uses the dri swap method value untranslated as the GLX fbconfig swapMethod,
so we can't enumerate these tokens arbitrarily, but rather need to make them
have the same values as the corresponding GLX tokens.
