For various reasons (see discussion at [1]) we would like an alternative
to `prove` for running test suites (including the unit tests) on
Windows.

[1] https://lore.kernel.org/git/pull.1613.git.1699894837844.gitgitgadget@gmail.com/

This series extends the existing `test-tool run-command testsuite` to
support running unit tests. In addition, it includes some small
cleanups:
* move t-basic out of the unit-tests directory
* don't hardcode the shell for running tests in `test-tool ... testsuite`
* don't hardcode a test name filter in `test-tool ... testsuite`
* add a test wrapper script to allow unit tests and the shell test suite
  to run in a single `prove` process

Changes in V4:
* Set TEST_SHELL_PATH when running the `prove` test target, and error
  out of run-test.sh if TEST_SHELL_PATH is not set.

Changes in V3:
* Added new patch (#7) to use the new test-tool runner for unit tests in
  Windows CI.
* Restored the explicit sort call in t/Makefile, for backwards
  compatibility with older GNU Make versions.
* Rebased the series on the latest jk/unit-tests-buildfix branch.
* Fixed header include order in patch #1.
* Removed a paragraph in patch #1's commit message that is obsolete now
  that we're building the list of test files from the sources rather
  than by globbing.
* Added a note in patch #2 that setting a NULL suite.shell_path will be
  used in a later commit.
* Clarified up some sloppy wording in commit messages and comments in
  t/helper/test-run-command.c.

Changes in V2:
* Rebased the series on the latest jk/unit-tests-buildfix branch.
* Patch 1: move t-basic to a test-tool subcommand rather than a new
  executable under t/t0080/
* New patch 2: get the shell path from TEST_SHELL_PATH in
  `test-tool run-command testsuite`
* New patch 3: remove the hardcoded filename filter in
  `test-tool run-command testsuite`
* Patch 4 (previously 2): simplified now that we no longer need to add
  any command-line flags to support unit tests
* Patch 5 (previously 3): avoid trying to run cmake *.pdb files by using
  the unit test list built in the makefile in jk/unit-tests-buildfix.
