Cleanup: move QWebChannel benchmarks into a separate subdirectory

Benchmarks should not be a part of common test-cases.
We normally have a different tests/benchmarks subdirectory for them.

This commit moves benchmarks from tst_webchannel into a new benchmark.
This requires defining a new class as a friend of QWebChannel and
QMetaObjectPublisher.
