Entering debugger scope should not make debugger active.

The motivation is that by only entering the debugger scope to call into
the debug context should not cause code to be compiled for debugging.

Support external startup data in V8.

If the embedder chooses, the 'natives' (library sources) and the
precompiled startup blob can be written to files during the build
process and handed over to V8 at startup. The main purpose would be
to reduce the size of the compiled binary for space constrained
platforms.

The build-time option is off by default. Nothing should change if
it's not enabled.

Add tests for FuncNameInferrer.

There were no explicit tests for FuncNameInferrer (though, some tests might
implicitly rely on it working properly in the common cases). Afaics, there were
no tests which would exercise inferring two byte function names or escaped
function names.
