internal/gocore: support Go 1.22 allocation headers

This change supports Go 1.22 allocation headers by identifying all the
heap pointers when enumerating spans. When looking over each span, we
check to see where the pointer data for each value lives, and then
enumerate all the pointers as needed.

This gets the goroot test passing again, which is a low bar... but it's
something.

While we're here, let's also get rid of a branch that only applied to an
unreleased version of Go 1.22.

Fixes #63359.
