Previously we had identified this error with the analyzer error code
CompileTimeErrorCode.WRONG_NUMBER_OF_TYPE_ARGUMENTS_CONSTRUCTOR, but
they're not the same error at all. As a result, code like this:
var x = new a.b.c<C>();
would lead to the bogus analyzer error text "The constructor '{0}.{1}'
doesn't have type parameters." (with the placeholders "{0}" and "{1}"
visible to the user).
With this change, the error text is the same as that from the CFE: "A
constructor invocation can't have type arguments after the constructor
name."

This test used `..` as a continuationToken (that is, it did not expect
a syntax error for `g(C<int, int> .. toString())`). This CL changes the
test to expect that to be a syntax error, and also eliminates the
static warning caused by using `?.` on a receiver with a known non-null
value (that's not relevant to the topic of this test, I just didn't
avoid it when the tests were written).

This allows local variables and other expressions, as long as the
static type is a generic function type, to be explicitly type
instantiated.
* Expressions with a non-generic function type cannot be type
instantiated.
* Expressions with a type of `Function` cannot be type instantiated.
* Expressions with other non-function types cannot be type instantiated.
This results in doubling-up of errors in a few situations. I think these
are generally rare occurrences, and tricky to prevent double reporting,
so I've left them for now.

This should handle all cases of constructor reference w/ explicit type
args; there aren't too many cases:
* named and unnamed constructors
* referencing class and referencing type alias
* prefixed class names and not-prefixed
* null-aware access (weird)
* bound on type parameter of class, and on type parameter of alias
error cases:
* cascade
* wrong number of type arguments

The test aliased_constructor_tear_off_test.dart expected torn off
constructors to be unequal even in cases where the same constructor
is torn off and instantiated with the same type argument (albeit a
non-constant type). That equality _should_ hold, and this PR makes
the change needed to give the test that expectation.
The test tear_off_test.dart was adjusted similarly.

Now that we have an AST and visitor support for the FunctionReference
structure (which represents `Expression<TypeArguments>` for various
kinds of expressions), we no longer need to error recover this as a
FunctionExpressionInvocation with synthetic arguments. The resolver
still doesn't resolve the syntax properly, but that's ok because it's
not permitted in valid code (for now we just treat it as having type
`dynamic`).
Fixes#46150.

This CL adds parser support for use of `<typeArguments>` as a
selector. This allows expressions like `List<int>` (type literal with
type arguments), `f<int>` (function tear-off with type arguments),
`C.m<int>` (static method tear-off with type arguments), `EXPR.m<int>`
(instance method tear-off with type arguments), and `EXPR<int>`
(tear-off of `.call` method with type arguments).
I will add parser support for `.new` as a constructor name in a
follow-up CL.

I started doing this the normal way, but the two codes appear to differ
only based on whether the field was final, and I don't think that factor
is important to the nature of the error, so I think a single code is
sufficient.

Add a test where a class that has no generative constructors
declares an instance variable which is final and has no initializing
expression. With https://github.com/dart-lang/language/pull/1130 this
is an error, and that error is expected by the test. Also test that
it is not an error to have an uninitialized final variable which is
abstract or external.
