http2: switch to new runtime-controlled debugging system

Remove `--debug-http2` as a compile-time feature and
make all debug statements available using `NODE_DEBUG_NATIVE=http2`
at runtime.

This probably makes the debugging-enabled case a bit slower due to
additional string concatenations, but switching to a runtime-checking
system makes debugging more flexible and can be applied more easily
to other parts of the source code as well.
