Erik Ernst c15eed1269 Added metadata to new function type syntax parameter specifications
In https://github.com/dart-lang/sdk/issues/30732 the concern was raised
that the new Function type syntax does not support metadata on
parameter specifications (i.e., on normalParameterTypes and on
namedParameterTypes).

The implication of adding support for metadata in these locations is
that `@required` can be used on function types, which is the motivation
for submitting 30732.

We have always had support on parameter declarations in function typed
parameter declarations (`void foo(@A() int f(@A() String s))`), so in
this sense there is no new semantics to worry about (Lasse: "it doesn't
mean anything anyway!").

This CL modifies the generic-function-type-alias.md informal spec to
include this kind of metadata support.
