This CL implements the resolution of function overloads based on
run-time checks of the type of arguments passed to the JS function.
For the moment, the only supported overload resolution is between

This makes src/inspector:inspector into a v8_component producing a
shared library in component builds. To enable this, all of its exported

This also inverts the dependency between src/inspector:inspector and
:v8_base_without_compiler, and instead makes d8 and some tests depend on

As a result, the no_check_targets exclusions list in .gn is reduced.

This moves all of the FunctionTemplateInfo code into templates.cc and
removes the inline keyword from BreakAtEntry which is moved out of
templates-inl.h. As a result templates-inl.h no longer depends on
shared-function-info-inl.h. This in turn uncovered lots of other missing
includes which are now in place.

The flag --trace-ignition-dispatches has been broken for a long time,
since it was not designed to work with bytecode handlers that are
generated ahead of time by mksnapshot. This splits the existing
--trace-ignition-dispatches logic into two separate parts:
1. A gn argument which instructs mksnapshot to include dispatch counting
in the bytecode handlers, and ensures that the Interpreter allocates
the array of counters, and
2. A runtime flag which enables the ignition-statistics extension which
implements the JS-accessible function getIgnitionDispatchCounters().

So far, initializer-expression evaluation was tied to setting global
values. We now need it to operate independently of globals, so that we
can implement new constant expressions like struct.new, which need their
arguments to be computed before they can be initialized.
Changes:
- Move type computation of WasmInitExpr into WasmInitExpr::type.
- Fix WasmInitExpr::type kRttSub case for rtts without depth.
- Introduce InstanceBuilder::EvaluateInitExpression().
- Rename InstanceBuilder::GetRawGlobalPointer() ->
GetRawUntaggedGlobalPointer().
- Simplify InstanceBuilder::InitGlobals using EvaluateInitExpression().
- Introduce ValueType::is_numeric.
- Add Simd128(byte*) constructor.
- Introduce WasmValue::CopyTo() for numeric types.

Instead of compiling a function with baseline immediately when the
interrupt budget is hit, we compile functions in batches to save some
memory protection flips on code pages.
This CL introduces batch compilation behind --baseline-batch-compilation
(enabled on future) and adds a flag
--baseline-batch-compilation-threshold to control the size of batches.

Generating C++ source files is very cumbersome using raw ostreams. This
CL introduces a few classes und the torque::cpp namespace that build an
abstraction of printing/formatting C++ source code (mostly functions for
now).
This is an initial implementation with a limited set of features and
uses. Landing features incrementally shall avoid huge CLs (+reviews) and
complex rebasing.
