The added field holds the interface signature type for a Procedure when
this is different from the class signature type (implied by the function
parameters and return type). This is needed for forwarding semi stubs
when its declared type is different from the called super member.

This adds a third reference to Field declaration, so that we know have
three references, one for each use case:
1) fieldReference used for initialization; in FieldInitializer and as
the key in the InstanceConstant.fieldValues map.
2) getterReference used for reading; in InstanceGet, StaticGet and
SuperPropertyGet
3) setterReference used for writing; in InstanceSet, StaticSet and
SuperPropertySet

We use an extension getter instead of an instance getter because
it doesn't conflict with any potential existing or future enums
which want an element named `name`.
Keeping the namespace for enum elements open is a priority.
We currently only reserve `index` and `values`.
BUG: https://github.com/dart-lang/language/issues/1511
Fixes language issue #1511, which is a long-standing request,
and should replace a number of alternative implementations
which are based on parsing the `toString()`.
This version has two fields on the shared superclass, the index
and private name, and has a separate `toString` for each `enum` class
which hard-codes that enum's class name.
An earlier version had both `"name"` and `"ClassName.name"` as fields
to be able to reuse the same `toString` method on all enum classes,
but that cost too much for JS compiled code.
Even having just `ClassName.` as a field and then combining inside
`toString` requires more code to create the enum instances.
Instead this version hardcodes the `ClassName.` string once
in the `toString` method, which means each enum class has its own
toString (which can *potentially* be tree-shaken then.)
This still tree-shakes slightly worse than the previous implementation
where every enum class had its own `index` and `_name` fields
independent of each other, which could then be tree-shaken independently.
However, the `index` was already made an interface member with the
addition of the `Enum` interface, so code which accesses `.index`
on something of the `Enum` supertype could prevent tree-shaking of
all enum classes' `index` fields.
Likewise any general access to the "name" of an enum would necessarily
do the same for the name.
This CL makes up for some of that by sharing more implementation
between enum classes.

Before this CL:
If a library (say lib.dart) imports a file (say part.dart) that's
actually a part (of some other library (say main.dart)) an error is
given, but the "fake library" shortly representing the part is still
"linked" into the libraries dependency list.
This means that the component returned from a compilation is different
from the combination of libraries one can get to if walking all
LibraryDependency's. This also means that if we serialize the component
we can't load it back in (https://github.com/dart-lang/sdk/issues/46706).
It furthermore means that we have two different entities with the same
fileUri and importUri.
This CL rewrites a such import of a part to instead be an import of the
"parent", i.e. if a library lib.dart imports part.dart that's a part of
main.dart an error is issued, and the import is rewritten to be an import
of main.dart instead. The same thing happens to exports.
This alleviates the problems (i.e. no crashing if trying to load the dill,
no referenec to a otherwise non-existing library etc), and has the added
benefit of probably being what the user wants: Anything defined in
part.dart (that isn't private) is still in scope from lib.dart.

As part of deprecating support for native extensions we are also
migrating away from legacy VM-specific `native 'name'` syntax
towards metadata based encoding which does not require any special
syntax.
This CL is a step 1 in migration:
- introduces support for `@pragma('vm:external-name', 'name')`
which serves as a direct replacement for `native 'name'`;
- all core libraries and tests are migrated to use the annotation;
Once this CL lands and rolls we will edit internal and external embedders
to eliminate uses of the native keyword (step 2) and finally remove
support for native keyword across our parsers (step 3).
