i965/compiler: Bring back the INTEL_PRECISE_TRIG environment variable
This was removed in d9546b0c5d and replced with the precise_trig driconf
option. However, we still need precise trig in the Vulkan driver so this
commit brings back the environment variable and compiler->precise_trig is
effectively the logical OR of the two.
