test: Simplify Jest config and expand coverage (#25013)

## **Description**

Our Mocha and Jest configuration has been messy because we're in the
middle of a migration from Mocha to Jest. Each file had to be explicitly
included in the Jest configuration or ignored in the Mocha
configuration. This was inconvenient and error-prone, and resulted in
some tests not being run at all.

~Both test configurations have been updated to use a shared list of
Mocha test files. There are only a few of these files left, and this
list should only get shorter as we migrate more tests to Jest. No
further configuration changes will be needed to add Jest tests.~

We have now finished migrating unit tests from Mocha to Jest, so this PR
now only affects the Jest configuration.

Note that the ESLint configuration has not been updated to use these
simpler globs to determine which tests use Mocha and which use Jest. I
tried doing that in this PR initially but it raised too many lint
errors, so that will come in a later PR. In the meantime, we may still
need to update `.eslintrc.js` when adding a new test of either type.
