The fact that the go line sets both the language version and the
GODEBUG compatibility version can be a problem, especially since
the go line is also required to be ≥ the go lines of any required
dependency modules.
This change adds a new 'godebug' line to go.mod and go.work
to allow setting the GODEBUG values for the entire module.
It also adds a new meta-value default=go1.21 that means
take the defaults from Go 1.21 no matter what the go line says.
These were discussed in proposal #65573.
Fixes#65573.

Per the note earlier in the page, GODEBUGs are maintained for a
minimum of two years (four Go releases). Not said but certainly
implied is that they are maintained for four Go releases from the
point where people started needing to use them.
Since people would start needing gotypesalias=0 in Go 1.23,
it can be removed in Go 1.27.

Additionally, the internal representation of a cookie in the cookiejar
package has been adjusted to align with the new representation.

This is the final CL in the series adding PGO preprocessing support to
cmd/go. Now that the tool is hooked up, we integrate with the build
cache to cache the result.
This is fairly straightforward. One difference is that the compile and
link do caching through updateBuildID. However, preprocessed PGO files
don't have a build ID, so it doesn't make much sense to hack our way
through that function when it is simple to just add to the cache
ourselves.
As as aside, we could add a build ID to the preproccessed file format,
though it is not clear if it is worthwhile. The one place a build ID
could be used is in buildActionID, which currently compute the file hash
of the preprocessed profile. With a build ID it could simply read the
build ID. This would save one complete read of the file per build
(cmd/go caches the hash), but each compile process also reads the entire
file, so this is a small change overall.
Fixes#58102.
