gprofng: add hardware counters for Appliedmicro processor

gprofng/ChangeLog
2024-08-15  Vladimir Mezentsev  <vladimir.mezentsev@oracle.com>.

	* common/hwc_cpus.h: New constant for Appliedmicro processor.
	* common/hwctable.c: Add the hwc table for Appliedmicro processor.
	* src/hhwc_arm64_amcc.h: New file.
	* src/collctrl.cc (read_int): Use strtol instead of atoi.
