[release-branch.go1.20] all: make safe for new vet analyzer
c32f1af 
The unused analyzer handles dot imports now, so a few tests
have picked up vet errors. This CL errors like:

context/x_test.go:524:47: result of context.WithValue call not used

This is a manual cherry-pick of CL 493598.

Updates #60058
Fixes #60927

Longtest builders are failing on 1.21 and 1.22 release branches (but not on tip and 1.20 release branch):

https://ci.chromium.org/p/golang/g/x-tools-go1.21/console
https://ci.chromium.org/p/golang/g/x-tools-go1.22/console

Since it's affecting first-class ports, it's blocking the monthly tagging workflow. Adding Soon label.

Mailed CL 554755 to pull in the change made in CL 554196 into release-branch.go1.22.
Mailed CL 554756 to backport the change in CL 554196 to release branch.go1.21.

The report 1 hr ago (#60058 (comment)) is the same Go commit and x/tools commit as the earlier one (#60058 (comment)). The difference is it came from LUCI builders instead of old builders.
