Move another batch of analyzer tests away from offset-based
assertErrorsInCode() expectations. Put expected diagnostics and context
messages directly in the source snippets instead, including multi-file
cases that need context markers in supporting files.
This keeps each diagnostic expectation next to the code that produces
it, making the tests easier to read and less fragile when surrounding
code changes. It also removes now-unused diagnostic imports and helper
parameters that were only needed for explicit ExpectedDiagnostic lists.
Update the diagnostic expectation utilities so stripping generated
marker lines preserves the retained source lines correctly.

Static field initializers are only run once and as such are cold code.
They should never be inlined into hot code that accesses the static
field.
Though right now `wasm-opt` will inline the static field initializers
e.g. if there's only one use of a static field (as it makes size a bit
smaller if we avoid the extra wasm function). That has the problem that
it may inline cold code into hot code. That hot code in return then gets
big and may not be allowed to be inlined into it's caller.
One can instruct binaryen to only inline functions with one caller up to
some size by passing `--one-caller-inline-max-function-size` (see [0]).
Though that can regress size.
So instead we specifically mark the function we know are cold to not be
inlined, namely static field initializer functions above a certain size.
This changes performance of a benchmark from [1] from
cascadeUnhoisted: 390000 us
to
cascadeUnhoisted: 138000 us
NOTE: This will cause some size regressions for e.g. e main module by
0.4-0.5% - but seems to be the right thing to do.

Updates the simplification of moving constat operands of comparisons to the right to correctly use the strictly swapped operand rather than the negated operand.
Also change the `flipOperands` function to a `swapped` getter to avoid confusion and be clearer that it returns a new value, rather than changing the current one. This better aligns with the Effective Dart guidelines for when to use a getter and how to name them.

When casting a getter return value that requires a covariance check, the
CFE inserts an AsExpression where both the operand type and
tested-against type are statically identical (the instantiated member
return type, e.g. Callable<void Function(num)>).
The types.dart optimizer previously assumed that because the static
types matched, the runtime type arguments must also match, and optimized
away the type-argument checks. However, in a covariance check, the
dynamic value returned is a supertype (e.g. Callable<void
Function(int)>) due to class parameter covariance.
This change safely rewrites the static operand type of a covariance check
by preserving the InterfaceType structure but using calculateBounds to
rewrite its type arguments to their upper bounds (falling back to Object?
or Object for non-interface types). This allows us to keep class-check
optimizations active while remaining sound.

We will want to deprecate the `analyzer/language/strict-casts` setting,
but we first need to ship an SDK to Flutter that offers the lint rule,
before we deprecate the setting, which will cause CI to fail (like a
Dart->Flutter roll).
When the deprecation is enabled, we can also ship the automated fix.

This reduces e main module by around -0.4% uncompressed
and -0.5% compressed
Value types don't have identiy, they are compared by value. As such
there's no need to have a unique int/double box for the same value -
each module can have their own box: The box identity cannot observed.
That in return means also we avoid exporting those from main module &
importing into deferred modules.

Measured on size of e main module (baseline is we don't embed
it in application code):
* embedding before: +16.5% uncompressed / +9.1% compressed
* embedding with this CL: +4% uncompressed / +4.3% compressed
When embeddeding deferred load list information into the app
(as opposed to a separate json file) we now use a more compact
encoding.
Specifically: Instead of encoding it as an array of an array of
strings (which are module names), we encode it as an array of an
array of module ids and construct the module name from the id.
To make the array of module ids more compact we utilize the fact
that we can sort them and encode in delta encoding (i.e. instead
of absolute module ids, encode the diff between previous module
id in the list).
We put the encoded module id lists in a data section and create
`WasmArray<WasmI8>`s from them at startup. When we trigger a load
we then decode them into the list of module names.
There's more opportunity to optimize it, but it's good to do
this as a first step.

When we built the added the original interactive refactors support, we supported the client telling the server which field kinds it can prompt for, so that if there were questions the client didn't support that did not have default values, the refactor could be hidden.
However, we only implemented one such refactor (Move to File) and the only field (destination URI) has a default value, so the client capabilities never have any effect.
Since we're replacing this support with the new "Interactive Forms" and don't intend to create any new refactors using the old system, this code is all redundant and therefore can be deleted.
