John Stiles 5e9388d170 Add support for conditional unit tests.
DEF_CONDITIONAL_TEST and DEF_CONDITIONAL_GPUTEST_FOR_xxxx_CONTEXTS will
allow unit tests to be considered or ignored based on a passed-in
boolean condition. DEF_TEST_DISABLED is now implemented as a conditional
test hard-coded with a "false" condition.

This allows macros (such as SKSL_TEST) to add unit tests based on the
result of a comparison.
