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 (cherry picked from https://googleplex-android-review.googlesource.com/q/commit:5f8117acd45348704629a8aa7bd2169a5ad6a547) Merged-In: I6317fdbce340a8e7cbf3020ad41386cf9915dd2d Change-Id: I6317fdbce340a8e7cbf3020ad41386cf9915dd2d
