Cross compile tools for ARM (aarch64)

[echiugoog]

Cross compile supporting toolchain (where possible)
For perf, I bumped up the version to get a newer version of perf that supports Neoverse V2 cores

processwatch has ARM support, but we can't crosscompile right now as we need an ARM kernel to do the btf dump
e.g.

src/bpf/insn/build.sh
${BPFTOOL} btf dump file /sys/kernel/btf/vmlinux format c > ${DIR}/vmlinux.h

Did a basic perf test on a Neoverse V2 guest to validate perf:

$ sudo ./perf stat -- sleep 1

 Performance counter stats for 'sleep 1':

Looks awesome. One issue with where to get the aarch64 binaries when building with the container.

[harp-intel]

When building through the build.sh script, and associated containers, tools should come from the "prebuilt" folder.

cp -r /prebuilt/tools/bin-aarch64/* internal/script/resources/aarch64

Does that make sense?

[echiugoog]

I'm running into this and some other issues as I work to cross compile and package perfspect. I'll pull the commits into this PR

[harp-intel]

Please limit commits to those necessary for building the tools and the perfspect binary, i.e., not the enablement of collecting metrics on ARM. Leave that for a second PR. Thanks.

Too bad turbostat is x86 only. It's really useful for telemetry.
