Merge #46138

46138: github-pull-request-make: set minimum testrace duration per test r=tbg a=pbardea

This change updates the minimum allowed duration for a test run under
race in CI to be configured on a per-test basis, rather than a
per-package basis.

When there are a lot of tests in a given package that need to be
stressed by testrace, the entire package may not be given sufficient
time to complete. For example, #45962 was not passing CI since many
tests were changed within one package.

Release justification: Non-production code changes.
Release note: None
