compiler-rt: sanitizer_common: use close_range() instead of looping (#114442)

_SC_OPEN_MAX is quite high on FreeBSD, which makes this close() loop a
quite obvious problem when attempting to do any kind of debugging in a
process that uses StartSubprocess. Switch to using close_range(2)
instead to close them all in a single syscall and dramatically reduce
the runtime and syscall trace noise

Linux has an equivalent syscall, but I do not have the capacity to test
that it works there, so this is limited to SANITIZER_FREEBSD for the
time being.
