EGL: Close Multifile Blobcache files after mapping
When loading entries from disk, we don't need to keep the
files open after mapping their contents.
Per mmap documentation:
After the mmap() call has returned, the file descriptor, fd, can
be closed immediately without invalidating the mapping.
https://man7.org/linux/man-pages/man2/mmap.2.html
This will prevent consuming excessive file descriptors, which
are a limited resource.
Added new test that ensures file descriptors do not remain open.
Test: libEGL_test, EGL_test, restricted_trace_perf.py
Bug: b/286809755
