tools/perf/build: Speed up auto-detection of features by adding a 'test-all' target

Concatenate all feature checks into test-all.c.

This can be built and checked faster than all the individual tests.

If test-all fails then we still check all the individual features, so
this is a pure speedup, it should have no effects on functionality.
