This test tried to get enough samples by varying the amount of work
done based on simulator vs. non-simulator builds. This didn't take
into account other things like release vs. debug, and some bots took
a very long time to run this test.

This CL uses the existing ProfilerHelper and sets a minimum number of
samples so that we can actually run the minimum amount of work for
any platform without manual tweaking.

This decreases runtime on x64.optdebug from 18.5 to 1.08s, and from
10+ min on x64.debug to 1.8s. arm.debug is ~4s now.

Just a cleanup, should not change behavior, although we will allocate
more handles in some cases.

Also re-orders some of the implementations of the interface to try
and keep things consistent.

Included cleanup: Change CodeEventDispatcher so that it now implements
CodeEventListener, given that it had that exact interface already.
Also remove the macro dispatch to try and make things a bit easier to
read.

Renderer hangs are possible with current limit (25). I'd like to know
what a limit of 15 does to benchmark performance, and see it's effect
on hangs.

This adds a {wasm::DebugInfo} struct which will hold the
{wasm::DebugSideTable}s for individual Liftoff functions, and will use
them to construct local scope information.

In the process:

* Rework the Torque definition of ScopeInfo to enable direct
  field-style access of ScopeFlags, removing some dead code in
  the process.
* Allow implicit FromConstexpr conversion from subtypes of
  'constexpr A' to other types. This makes it possible/easy to
  convert constexpr versions of enums to other types, since the
  constexpr version of the enum isn't addressable. It's namespace
  isn't a valid namespace and is an implementation detail anyway.
* Cleanup LanguageMode: Language mode is now an enum and directly
  mirrors the C++-side definition rather than being a Smi. With
  the changes above, a new type LanguageModeSmi is introduced
  that is the Smi representation of LanguageMode that can be
  implicitly casted from constexpr LanguageMode values.

When opening DevTools, make sure that Wasm modules properly show up,
aka are reported via "Debugger.scriptParsed" events. Previously these
scripts corresponding to Wasm modules had been filtered out explicitly
(accidentally).
