Open one cache DB part at a time for a multi-part cache to reduce number
of FDs used by the cache. Previously multi-part DB cache instance was
consuming 100 FDs, now it's 2 and cache files are opened when cache
is read or written instead of opening them at the init time.
Fixes: fd9f7b748e ("util/mesa-db: Introduce multipart mesa-db cache")
Closes: https://gitlab.freedesktop.org/mesa/mesa/-/issues/11776
