`FutureOr<T?>` is already nullable, because `FutureOr<T?>` ==
`FutureOr<T | Null>` == `Future<T | Null> | T | Null`. So the second
`?` is redundant.
Also fix a bug where we were treating a `Null` type as `Never` if we
couldn't find a reason to require it to be nullable; this was
inconsistent with how the FixBuilder was handling `Null` (which is to
leave it unchanged).

This change produces UNUSED_ELEMENT hints for optional parameters
for which no arguments are ever explicitly given, under the following
circumstances:
* parameter is for a constructor, method, or top-level function which
is not accessible outside the library,
* function is never torn-off (all bets are off once its been torn off),
* method does not override a method in which the matching parameter is
required,
* method does not override a method with a matching paramter, in which
an argument is given for the matching parameter.

There were two problems:
- EdgeBuilder wasn't handling the extension override syntax at all,
causing a crash.
- FixBuilder wasn't overriding the behavior of
ExtensionElement.extendedType, causing a star type to be used as a
context for the target expression; this prevented the fix builder
from realizing when it needed to insert `!` after the target
expression.
Fixes#42455.

EdgeBuilder wishes to do its own GLB type-joining, as does FlowAnalysis.
When FlowAnalysis pushes a promotion in ifNullExpression_rightBegin,
and then in write, and then pops those two promotions to join them in
ifNullExpression_end, EdgeBuilder is not given a chance to make its
own GLB node. Instead promotion never happens: the DecoratedType which
is the variable's type is promoted to non-nullable, for the left side.
The DecoratedType for the right side expression is not considered
non-nullable, so the FlowAnalysis.join will always fail to promote.
TypeOperations.adjustPromotedTypes solves this. It is a no-op in all
implementations except in EdgeBuilder.
Additionally FlowAnalysis.write's promotion fails for the same reason:
the only type of interest is the declared type made non-nullable, and
no matter what, the writtenType is not a subtype of this.
TypeOperations.forcePromotion solves this. It is a no-op in all
implementations except EdgeBuilder.

Previously the API was general, exposing a `numPhases` integer, and
providing a generic processing function with a `phase` argument. This
was necessary back when migration was built into DartFix (because
different kinds of fixes had different numbers of phases), but now
that migration is a separate tool, it gets in the way because it makes
it difficult for the caller to have different behaviors in different
phases.
This is a prerequisite for making it possible to have some files
analyzed but not finalized (which is in turn necessary for handling
generated files).

Previously, MigrationCli.run() would always return, but it would set

made it necessary to thread a lot of tricky logic around to ensure
that we would exit quickly if an error occurred. This CL switches to
using an exception, so we get the same effect automatically.
