anv: Enable nir_opt_access

This commit will enable pass for searching readonly / writeonly
access when it's missing.

We don't support shaderStorageImageReadWithoutFormat
and the optimization pass causes those shaders to
take the write-only path which does support formatless.

Following games are affected with positive result:
 - Wolfenstein: Youngblood
 - Wolfenstein II: The New Colossus https://gitlab.freedesktop.org/mesa/mesa/-/issues/3138
 - Rage 2 https://gitlab.freedesktop.org/mesa/mesa/-/issues/5791
 - The Surge 2 https://gitlab.freedesktop.org/mesa/mesa/-/issues/5805
 - Metro Exodus https://gitlab.freedesktop.org/mesa/mesa/-/issues/4703
 - DOOM Eternal https://gitlab.freedesktop.org/mesa/mesa/-/issues/4273
