Subject: test: support running functionaltests in parallel by directory
 (#37918)

Define a CMake target for every subdirectory of test/functional that
contains functional tests, and a functionaltest_parallel target that
depends on all those targets, allowing multiple test runners to run in
parallel.

On CI, use at most 2 parallel test runners, as using more may increase
system load and make tests unstable.
