* 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
* Add support for Apple M1 AArch64 SoCs
Completely based on #150. Thanks to @sbehnke!
+ Refactoring to accomodate the new source tree
+ Adding more feature flags
* revert minimum version to 3.0
* Update introspection table
* Simplify logic for Apple HAVE_SYSCTLBYNAME

* Add Windows Arm64 support
To add Windows Arm64 support was added detection of features via Windows API function IsProcessorFeaturePresent. Added _M_ARM64 to detect CPU_FEATURES_AARCH64 macro on Windows. Added initial code for Windows Arm64 testing and provided test for Raspberry PI 4. We can't use "define_introspection_and_hwcaps.inl" as a common file for all operating systems due to msvc compiler error C2099: initializer is not a constant, so as a workaround for Windows I used separate "define_introspection.inl"

* [CMake] Add windows_utils.h to PROCESSOR_IS_AARCH64
* Add detection of armv8.1 atomic instructions
* Update note on win-arm64 implementation and move to cpuinfo_aarch64.h
* Remove redundant #ifdef CPU_FEATURES_OS_WINDOWS
* Add note on FP/SIMD and Cryptographic Extension for win-arm64
* Add comments to Aarch64Info fields
Added comments to specify that implementer, part and variant we set 0 for Windows, since Win API does not provide a way to get information. For revision added comment that we use GetNativeSystemInfo
This commit helps with platform code separation (fixes#3). It should also help with the build as we can simply include all `impl_*.c` files regardless of OS / arch.
Note: this patch contains breaking changes in `include/cpu_features_macros.h`
- `CPU_FEATURES_OS_LINUX_OR_ANDROID` does not exist anymore
- `CPU_FEATURES_OS_FREEBSD`, `CPU_FEATURES_OS_ANDROID` and `CPU_FEATURES_OS_LINUX` are now mutually exclusive (i.e. `CPU_FEATURES_OS_ANDROID` does not imply `CPU_FEATURES_OS_LINUX`)
- `CPU_FEATURES_OS_DARWIN` has been renamed into `CPU_FEATURES_OS_MACOS` to be able to target non-Mac Apple products (IOS, TV, WATCH). They are now targetable with `CPU_FEATURES_OS_IPHONE`. This matches Apple naming convention described in [this stackoverflow](https://stackoverflow.com/a/49560690).
This is a non functional change, it allows:
- Getting rid of `unix_features_aggregator`
- Have a single blob describing the features
- Fix wrong mocking of `hwcaps`
Downside: abuse of macros makes the code slightly magical and harder to understand.
It think it's still an improvement over the current situation as there's less repetition and less chances to get something wrong.
Fixes#4. This is based on #115 with a few modifications:
- Removed use of __builtin_cpu_supports since it relies on cpuid and doesn't improve on the current situation,
- Added detection for all of sse, sse2, sse3, ssse3, sse4_1 and sse4_2,
- Added tests for Atom, Nehalem, and P3 processors,
Thx to @gadoofou87 for providing the original PR.
