[roll] Roll fuchsia [starnix] Add proc/self/stat read benchmark to microbenchmarks

Introduce a microbenchmark that measures the time taken to open,
read, and close `/proc/self/stat`.

To simulate different process sizes (scales), the benchmark creates
a configurable number of anonymous memory mappings using `mmap` before
performing the reads.

This benchmark runs as a Linux userspace process inside Starnix.
