Import TestRunner library into chromium.

The reasons for the move are:

- it's actually a blink embedder, so it can't use blink/wtf types
- it can't use base either
- we want to replace CppBoundClass with gin::Wrappable, not possible in blink

In the first step, this is mostly a 1:1 copy (except for include paths).
Follow-up CLs will move the test plugin and layout tests helpers and
clean up the coding style
