*: use skip.* methods, not TB.Skip

This commit introduces a new family of methods in the testutils/skip
package:

- WithIssue, WithIssuef: skip a test temporarily, linking to a GitHub
  issue.
- UnderRace, UnderShort, UnderStress, UnderStressRace: skip a test when
  run under the race detector, -short flag, stress build, or stressrace
  build, respectively.
- IgnoreLint, IgnoreLintf: skip a test for another reason, without
  bothering the linter.

It also removes all naked TB.Skip and TB.Skipf calls, replacing them with
one of the above skip package methods, and adds a linter to ensure that
naked TB.Skip is never used.

This opens the door to performing more analytics on our skipped tests
and benchmarks, because of the extra structured data these methods
provide.

Release note: None
