Add a new kind of constant context in the body builder for expressions
that must be constant but where constness is not inferred.
This context is used for parameter default values and initializing
expressions for non-final fields in classes containing at least one
const constructor.

Original PR was reverted because it broke hot-reload bots. This CL adds steps to initialize kernel_service compiler for child isolate. Compiler is needed to support hot-reload request. Child isolate's compiler is created from full kernel file produced by main isolate's compiler. Changes since original PR are pkg/vm/bin/kernel_service.dart in pkg/vm/lib/incremental_compiler.dart.
Further this CL changes kernel fingerprint calculation for interface types so it calculates the hash of the canonical names themselves, rather than indices(that might change from one compilation to another).
This reverts commit 63fd8f63e6.

The CL is reverted because it didn't account for the case when a check
of a user-specified type argument against the bound depends on another
type that is only known after type inference is done.

If a field is initialized with null (either explicitly or implicitly),
field store can be omitted in bytecode. In such case, bytecode should
still convey the information about this initialization to VM for
field guards to work correctly.

Implement the feature spec for checking returns against inferred
function return types:
https://github.com/dart-lang/sdk/blob/master/docs/language/informal/invalid_returns.md
with the change that an invalid return without a subexpression is
a warning, not an error. This is because it is a warning in the
analyzer and it would be a breaking change to turn it into an
error.
The check for valid returns is moved to exactly where we handle
returns, rather than in ensureAssignable which is used as a
helper in a lot of places. A bug in type inference was fixed: we
would use `void` for the type of return without a subexpression
instead of `null`. To accommodate that we would use a
non-standard subtyping relation for returns. This could lead to
us inferring a return type of `void` in cases where we should
not.

E.g. `new Map<String>` is now reported as an error.
Note that this does not add a check for whether correct types are given,
so e.g.
```
class Foo<X extends num> {}
main() {
new Foo<String>();
}
```
is not caught by this fix.
Fixes#32972, #32281.

Prior to this change we only had fileOffset which points to the name.
This CL adds a field - startFileOffset - that points to the start
(e.g. 'static', 'factory', the return type or any presiding annotation
(including '@')), as well as fixing `Function::GetSource` in the VM to
fix a crash when using mirrors to ask for the source of a function or
constructor.
The field is added to procedures, constructors and classes.
The latter changes the location of classes with annotations to be
the position of the annotation. This is on-par with --no-preview-dart-2.
The change in regards to procedures and constructors mean, that both
the location and the source (from .location and .source on a
MethodMirror) will change to include any annotations. This is a
different behavior than --no-preview-dart-2.
Closes#33271.
