xcapture v3 and xtop first release

[tanelpoder]

What's Changed

The first proper release of xcapture eBPF thread level activity tracker + sampler and a reference implementation xtop tool, showing how to use this data for dimensional performance analysis.

The xcapture binary uses modern eBPF, therefore it can be compiled once, into a single executable binary and copied to any other server with a sufficiently high GLIBC and kernel version (5.11+).

If you love downloading and running binaries from random GitHub accounts, you can download the xcapture (or xcapture-oldkernel) binary directly from this release even without having to build anything.

Since this is a first and major release, lots of things have changed, I will cover the functionality and details in future blog posts.
