This CL replaces the equirecursive type system for wasm-gc with the isorecursive hybrid type system presented here: https://github.com/WebAssembly/gc/issues/257. In broad strokes, this includes the following changes: - In the module decoder, remove equirecursive types. Implement recursive type groups, subtype definitions, and function/struct/array definitions. Treat nominal modules as syntactic sugar of an isorecursive module, where all types belong in the same recursive group. - Remove rtt.sub and all related infrastructure. - Change subtyping to work with explicit supertypes only. - Add ValidSubtypeDefinition in subtyping, to check that subtype declarations are valid during decoding. - Remove the subtyping cache. - Add support for functions to have specific signature index in WasmModuleBuilder and in test-gc.cc. - Adapt tests. Current restrictions: - Recursive groups are not stored beyond decoding. - Type canonicalization is not implemented. No tests relying on types being considered identical post-canonicalization. - No cross-module subtyping is possible. Tests relying on cross-module subtyping have been commented out.

With this CL, externref parameters are supported by the generic wrapper. Externref parameters get handled in a separate loop which runs after the loop which converts primitive type parameters from JavaScript values to WebAssembly values. Externref parameters get handled separately because the conversion of primitive type parameters may cause a GC, and it would be hard for the GC to identify stack slots which contain reference parameters which have already been processed. As an optimization we remember in the first loop if we have seen a reference parameter. For functions without a reference parameter we would not iterate the parameters for a second time.

Previously, literals in Torque were stored as double values, which made it impossible to precisely represent 64 bit integer values. This CL replaces the old literal expression with an integer and floating point literal expression that are unbounded in size. We allow implicit conversion of these literals to arbitary integer and floating point types respectively and insert a corresponding bounds check into generated CSA. Changes in the reland: Simplified IntegerLiteral to single digit.

This CL replaces 'InvalidArgument' with 'ServerError' for Runtime#getExceptionDetails. The reason is that the error we raise is on the application level, allowing the DevTools frontend to handle it to a certain degree. 'InvalidArgument' errors would be interpreted as "something went really wrong", which is not the case here.

When reparsing the class scope to collect initializers in sloppy mode, the class scope may still have a scope info without any allocated variables. If its outer scope doesn't have an outer scope (which means the outer scope in the optimized scope chain becomes the script scope), we should also set the scope info in the script scope as is done in Scope::DeserializeScopeChain() for the scope resolution.

This patch takes advantage of memory information from the module to avoid unnecessary reloads of the SSA environment after a Wasm call. As far as I can sse, the SSA envinronment consists of the mem_start and mem_size values. Both these values cannot ever change if: initial_mem_size == max_mem_size. Although this should be obviously true for memories defined in the module itself, some explanation may be necessary for imported memories. During module instantiation, the imported memory is checked as part of InstanceBuilder::ProcessImportedMemory. The following properties are verified: 1) The current size of the imported memory is >= the initial declared size 2) The maximal size of the imported memory is <= the maximal declared size The effective maximal limit will be min(imported_max, declared_max), hence the optimization will only trigger if the imported memory is already as large as it can be. Since memory growth is impossible, there is no point in reloading the environment anyway.
