We have number of methods that can be actually implemented in blink but need
different code for testing, I'm not sure if we want to add these impl methods
exposed here for all those methods.

Could we- or does it make sense to rather implement these as a default impl for
(un)registerMemoryDumpProvider and have empty impl in other subclasses like
TestBlinkWebUnitTestSupport when necessary?

BLINK_PLATFORM_EXPORT virtual void (un)registerMemoryDumpProvider(...);

Done.
