Subject: [PATCH] blender: use release config

This ensures that we at least default to the config that upstream
Blender uses. Remove any config that we have that is redundant with [the
current upstream][1]. Need to explicitly turn off
`WITH_CYCLES_CUDA_BINARIES` in non-CUDA (as release build will turn it
on) and turn off `WITH_CYCLES_DEVICE_ONEAPI` (as it was previously
implicitly off and we do not currently support it).
