Previously, we sent a critical low memory pressure notification when
attempting to commit WASM code when the code manager was near the
limit for total amount of code allocated.
https://chromium-review.googlesource.com/c/v8/v8/+/1073412 "fixed" that,
but it causes OOMs on Windows.
Since we no longer have the isolate on the code manager, and thus cannot
send this notification on commit, send the notification upon the next
module creation.
This is still not optimal, but should fix OOM issues for lots of
small modules on Windows.

The {WasmSharedModuleData} struct was introduced to hold data common to
all wasm instances belonging to the same module. The idea was to keep
"internal state" separate from the JS-facing {WasmModuleObject}. Since
this objective has no real value, and we already store some internal
data on the {WasmModuleObject}, this CL merges these two objects.

In the process:
- Add strict ordering of Types so that name mangling is consistent
and build time. Previously, the UnionType stored the union's
types in a std::set<const Type*>, which did not have a consistent
ordering of the types in the set.
- Add a int31 type to enable consistency and correctness of
handling of 'constexpr int31' values on the C++ side.
- By removing the "implicit" keyword for operators, there is now
one less difference between operators and calls, another
incremental step in unifying operators and calls.
- Enable external (i.e. C++-defined) generic specializations
- Add CSA support for checking double ElementsKinds, including
tests.
- Clean up some constexpr/non-constexpr handling of ElementsKinds.

This CL adds a TFS stub for RegExp#test and moves several checks to
the JSCallReducer. In particular, the JSCallReducer checks that
- property {exec} on the regexp is still the original exec
- property {lastIndex} on the regexp is a non-negative smi
The stub does not repeat these checks in release mode.
This effectively means that if the regexp is known, we can perform these
checks at compile time, and get away with a map dependency.
