[AUTOFDO] Enable autofdo tests for aarch64
autofdo tests are now running only for x86. This patch makes it
run for aarch64 too. Verified that perf and create_gcov are running
as expected.
gcc/ChangeLog:
* config/aarch64/gcc-auto-profile: Make script executable.
gcc/testsuite/ChangeLog:
* lib/target-supports.exp: Enable autofdo tests for aarch64.
