Adds checks for the following cases:
- Type arguments to createStaticInteropMock are correct
- No missing members in implementing class
- Inherited and non-overridden @staticInterop members are implemented
- Dart class can implement through inheritance and mixins
- Implemented members are correct subtypes of @staticInterop members
- Potential extension member conflicts that are attempted to be
resolved through subtyping rules

Default parameter values are implemented in dart2wasm via caller-side
substitution. When the same parameter has different default values
across different implementations within the same selector, a
special sentinel value is passed by the caller, and the callee
checks for this value and substitutes the actual default value.

Changes the representation of closures to include a vtable with entry
points for the various ways in which the function can be called.
For each combination of type parameter count and positional parameter
count, the names of named parameters occurring together with that
combination are partitioned into clusters such that any combination of
names that occurs together is contained within a single cluster.
Each combination of type parameter count and positional parameter
count gets a vtable layout for signatures without named parameters,
plus one for each cluster of parameter names belonging to the
combination.
Each vtable layout will have an entry for each number of positional
arguments from 0 up to the maximum number for the signature, followed
by an entry for each (non-empty) combination of argument names from
its cluster that occurs in a function call in the program.
This layout scheme is consistent with function subtyping in the sense
that if signature B is a subtype of signature A, then the Wasm struct
for the vtable layout corresponding to B is a subtype of the Wasm struct for the vtable layout corresponding to A, i.e. the fields in the layout
for A is a prefix of the fields in the layout for B.

Instead of using top types for the parameters and return of the
implementation function for a function expression or local function,
use precise types and generate a wrapper function with top types that
casts the parameters and calls the implementation function.
This unifies the wrapper function generation with tear-offs, setting
the stage for the upcoming generalization to support type parameters
and optional parameters.
The change also brings some benefits in its own right:
- Arguments to closures are converted once instead of at every use
- Direct calls to local functions avoid the conversion of arguments
Also add source location to closure function names and generally avoid
parentheses in function names, as they are confusing in stack traces.

This splits the type hierarchy into three separate hierarchies with
the top types `any`, `func` and `extern`.
Update d8 to 10.6.91, which switches to the new type hierarchy.
Also, all ref shorthands for abstract heap types are now nullable, so
the type emitter in the `wasm_builder` is updated to follow that scheme.
To reduce confusion about the nullability of abstract reference types,
these now all require the nullability to be specified explicitly.

This implementation has a number of limitations:
- Returning a Future from an async function is not supported.
- Every async call switches to a new stack. A later optimization will
stay on the same stack if the call is directly awaited.
- Exceptions that cross async boundaries do not receive full stack
traces including the async suspension points. The stack trace of the
final exception just reflects the stack trace for the outermost
async call.

Also, the --experimental-wasm-nn-locals options has been removed,

This is the last version before the (backwards-incompatible) change

DDC should compile the entire sources and outline dill in one step.
dart2wasm operates similarly, and so only needs the modular transformer.
dart2js moves the erasure to a global transform.

outline stubber.

With the decision to support non-nullable locals in WasmGC as per
https://github.com/WebAssembly/function-references/issues/44 the
support in dart2wasm for forcing all locals to be nullable is no
longer needed.
This CL removes that support and cleans up some related nullability
issues. Specifically:
- Remove the `--local-nullability` and `--parameter-nullability`
commandline options. These are now always enabled.
- Clean out special cases around forced nullable locals throughout the
compiler.
- Make `thisLocal` and `preciseThisLocal` always non-nullable.
- Make `returnValueLocal` (for storing the return value of `return`
statements inside `try` blocks with `finally`) always defaultable,
since its initialization flow crosses control constructs.
- Make type argument parameters non-nullable.
- Make non-nullable `FutureOr` translate to a non-nullable Wasm type.
- Implement the "initialized until end of block" validation scheme
in the Wasm instruction validator.
- Run tests with the `--experimental-wasm-nn-locals` option. This
is likely going away soon, but for now we need it.
