Add FreeBSD Arm64 support (#295)

Browse Source 
* Add FreeBSD Arm64 detection

Getting all the features is handled by reading /var/run/dmesg.boot. Feature detections were taken from the freebsd kernel code sys/arm64/arm64/identcpu.c

* Add FreeBSD Arm64 tests

* Add flagm, flagm2 and rng detection

* Add HWCAP FreeBSD AArch64

* Update include to use linux hwcaps for powerpc

* Add FreeBSD aarch64 impl

* Separate Hwacps to freebsd and linux implementation

* Add aarch64 midr_el1 implementation

* Add detection hwcap cpuid to hwcaps.h

* Add MIDR_EL1 tests
