Collect ArmCpuInfo data

[hrw]

I got some idea around AArch64 feature flags. But for this I need some more data than Linux provides in /proc/cpuinfo file.

Need to run ArmCpuInfo in EFI shell.

This gives much more data to process.

Example from Rockchip RK3588:

Shell> ArmCpuInfo.efi
ArmCpuInfo v1.3.0
