gh-109566, regrtest: Add --fast-ci and --slow-ci options (#109570)

* Add --fast-ci and --slow-ci options to libregrtest:

  * --fast-ci uses a default timeout of 10 minutes and "-u all,-cpu"
    (skip slowest tests).
  * --slow-ci uses a default timeout of 20 minues and "-u all" (run
    all tests).

* regrtest header now lists test resources.
* Makefile changes:

  * "make test", "make hostrunnertest" and "make coverage-report" now
    use --fast-ci option and TESTTIMEOUT variable.
  * "make buildbottest" now uses "--slow-ci". Remove options which
    became redundant with "--slow-ci".
  * "make testall" and "make testuniversal" now use --slow-ci option
    and TESTTIMEOUT variable.
  * "make testall" now uses "find -exec rm ..." instead of
    "find ... -print|xargs rm ...", same as "make clean".

* GitHub Actions workflow:

  * Ubuntu and Address Sanitizer jobs now use "make test". Remove
    options which became redundant with "--fast-ci".
  * Windows jobs now use --fast-ci option.
  * Use -j0 to detect the number of CPUs.

* Set Makefile TESTTIMEOUT default to an empty string, since
  --slow-ci and --fast-ci use different default timeout. It's now
  accepted to pass "--timeout=" to regrtest: treated as not timeout.
* Tools/scripts/run_tests.py now uses --fast-ci option.
* Tools/buildbot/test.bat now uses --slow-ci option. Remove
  --timeout=1200 option, redundant with --slow-ci.

   You can use the configure :option:`--enable-optimizations` option to make
   this the default target of the ``make`` command (``make all`` or just
   ``make``).
-* ``make buildbottest``: Build Python and run the Python test suite, the same
-  way than buildbots test Python. Set ``TESTTIMEOUT`` variable (in seconds)
-  to change the test timeout (1200 by default: 20 minutes).
+
+* ``make test``: Build Python and run the Python test suite with ``--slow-ci``
+  option. Variables:
+
+  * ``TESTOPTS``: additional regrtest command line options.
+  * ``TESTPYTHONOPTS``: additional Python command line options.
+  * ``TESTTIMEOUT``: timeout in seconds (default: 20 minutes).
+
+* ``make buildbottest``: Similar to ``make test``, but use ``--slow-ci``
+  option and default timeout of 20 minutes, instead of ``--fast-ci`` option
+  and a default timeout of 10 minutes.
+
 * ``make install``: Build and install Python.
 * ``make regen-all``: Regenerate (almost) all generated files;
   ``make regen-stdlib-module-names`` and ``autoconf`` must be run separately
