Rename functions in Port related to wptserve and add a helper function.
This is a refactoring CL which should cause no behavior changes.
In this CL:
(1) Rename is_wpt_enabled -> is_wptserve_enabled
(2) Rename is_wpt_test -> is_wptserve_test
(3) Add should_use_wptserve (= is_wptserve enabled and is_wptserve_test).
The rational for (2) is that many (most) tests in imported/wpt behave the
same if they're run with wptserve and with file://; only a smallish number
of the tests behave differently. It may be faster to run the tests if we
only use wptserve for the tests that require it; so later we may want
to change is_wptserve_test to check some things, e.g. wptserve header
files in the directory; or ".http." or ".https." in the file name.
