runtime: GODEBUG=tracebacklabels=1 for 1.27+
https://go.dev/cl/742580 updated the goroutine label format in
tracebacks to only quote the values under some circumstances, and use a
more broadly acceptable format. Flip the GODEBUG=tracebacklabels default
for go 1.27+ modules.
Notably, tracebacklabels is marked as Opaque to avoid some diciness in
maintaining a usage metric in signal handlers, etc. (where mutex
acquisition may be problematic)
Also, update the go 1.27 release notes to call out the new feature.
Updates #76349
