[v2] go: add ptest support

Add ptest infrastructure to test the Go standard library.

- Run 'go test -short std' via run-ptest script
- Install source tree and pkg/include headers
- Create VERSION file for architecture detection
- Exclude multi-arch binary testdata to avoid QA errors

Test results: 237/253 pass (93.7%) on qemux86-64.

Known issues:
- debug/elf, debug/pe, debug/plan9obj, internal/xcoff: missing binary testdata
- time: requires embedded timezone data
- net/http: requires unstripped go binary
- testing, go/types: minor edge cases

Changes in v2:
- Exclude .elf* files to fix QA arch errors on all architectures
- Exclude *-x86-64* files to fix additional arch-specific test binaries
- Tested on x86-64, x86, aarch64, and arm builds

Having the golang ptest running on x86 and arm is a great improvement for
the project.
Thank you very much for this patch.

Hi Pratik,

We might need to increase QEMU memory size. Did you had similar issues
on your side?

Thanks,

Hi Mathieu,

Thanks for testing!

Yes, Go ptest requires significant RAM due to on-the-fly compilation during testing.
On my setup (qemux86-64 with 4GB RAM), tests complete successfully in ~45 minutes.

The minimum RAM requirement appears to be ~2GB. With less RAM, the OOM killer
terminates compile processes as you've seen.

Options:
1. Increase QB_MEM for go-ptest in the recipe

This is similar to other resource-intensive ptests like gcc or llvm.

What would be the preferred approach for OpenEmbedded-Core?

Thanks,
Pratik
