[issue18492] Allow all resources if not running under regrtest.py

[Zachary Ware]

Zachary Ware added the comment:

Here's a new and better patch.  This patch keeps the regrtest_run global in support and moves the regrtest-or-not check into is_resource_enabled to make is_resource_enabled, requires, and requires_resource consistent with each other and in a way that still allows explicitly setting support.use_resources.  The real change is confined to Lib/test/regrtest.py and Lib/test/support/__init__.py, the rest of the patch is cleanup allowed by the change (except for test_decimal, which has a minor change required to allow one of the command line options to that script to work).
