The approach to creating compiler dispatcher jobs for inner functions after
they had been parsed didn't provide the startup benifits we hoped for due
to the need to hold onto the whole zone memory AST while waiting for the
jobs to complete.
This CL removes the ability to create these compilation jobs (which was never
enabled by default anyway). Going forward we will potentially use the
parser task approach to parse+compile inner functions in their own job.

This CL moves us much closer to the point where we can remove debugger-script.js and usage of debugger context from inspector.
There are three main parts left:
- managing breakpoints,
- inspecting stack and scopes (this CL),
- LiveEdit.
In this CL I moved all stack/scope inspection to native. As side effect running debugger and inspector tests are 10-20% faster (it's significant since not all of tests requesting break).

The only place we need fixed arrays is on the compiled module, to support

The CL aids with getting wasm of the GC heap, by reducing the places

Move ScopeInfo allocation out of DeclarationScope::Analyse and do it later
in the compile when finalizing unoptimized code generation. This is to enable
scope analysis to be done without heap allocation so it could run off-thread.

This is so that we can distinguish hash tables by instance type. We can
then introduce maps for each kind of hash tables to further distinguish.

We currently have a fixed limit of 256 characters for error messages
generated in the decoder. However, we sometimes embed names in it,
which makes it easy to generate a crash by using long names (e.g. for
exports) in invalid wasm modules.
This CL fixes this by switching to a stream based interface, allowing
to pass arbitrary objects to be printed. With this interface, we can
easily limit the length of output later.

Add a third parameter to {AsHex} which specifies whether the prefix
"0x" should be printed. Also, add the {AsHexBytes} helper which
outputs the hex number as individual bytes separated by a whitespace.
Also add unit tests for both helpers.
Both helper will be used in an upcoming refactoring of wasm error
messages:

Extend the errors.js mjsunit test to also check for the message in the
generated errors. This will help catch bugs later, e.g. when
refactoring the way we output errors:

Drive-by 1: Fix a superfluous period in one error message.
Drive-by 2: Fix a weird exception catching construct in the test.
