gopls/internal/telemetry/cmd/stacks: generate CodeSearch links

This CL causes the stacks command to mark up each stack as a
set of links to CodeSearch. In order to do that, it needs to
build the gopls executable at the correct version of gopls and Go
and for the right GOOS and GOARCH, read the pclntab out of the
executable (which is the only authority on how to decode the
symbol names that appear in the stack counter), and then
construct CodeSearch URLs from (version, file, line) triples.

The expensive steps are cached in /tmp/gopls-stacks so that they
are paid infrequently in a typical stacks run.

See https://github.com/golang/go/issues/67288 for an example
of the updated output.

Fixes golang/go#64654
