Move most of the implementation of AdjustAmountOfExternalMemory to v8.h

This reduces the overhead of reporting allocations to v8 to an

Support external startup data in V8.

[Retry of crrev.com/293993021, which caused problems with 'ninja all' in Chromium. First patch set if a clean apply
of crrev.com/293993021. Subsequent sets are the actual fix
for that issue.]

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.

V8 can clear exception pending message, when should not do this.

The case:
v8::TryCatch try_catch;
CompileRun(try { CEvaluate('throw 1;'); } finally {});
CHECK(try_catch.HasCaught());
CHECK(!try_catch.Message().IsEmpty());

CEvaluate is native call. Last check is not passed without patch. Patch contains test TryCatchFinallyStoresMessageUsingTryCatchHandler with more details.
