[PATCH v2 5/8] app/test: define unit tests suites based on test macros

[Bruce Richardson <bruce.richardson@intel.com>]

Rather than having the test suites listed out in the meson.build files
and having to have them enabled/disabled selectively based on what libs
are being built, pull the tests to run from the source files which were
added to the build.

Most test suites require no additional info other than the list of test
names in the suite. However the fast-test are special that they have
additional parameters associated with them. This requires some
additional work in the test extraction script and in the meson.build
file for processing the output.
