George Kalpakas bb6a3632f6 refactor(ivy): correctly type class declarations in `ngtsc`/`ngcc` (#29209)
Previously, several `ngtsc` and `ngcc` APIs dealing with class
declaration nodes used inconsistent types. For example, some methods of
the `DecoratorHandler` interface expected a `ts.Declaration` argument,
but actual `DecoratorHandler` implementations specified a stricter
`ts.ClassDeclaration` type.

As a result, the stricter methods would operate under the incorrect
assumption that their arguments were of type `ts.ClassDeclaration`,
while the actual arguments might be of different types (e.g. `ngcc`
would call them with `ts.FunctionDeclaration` or
`ts.VariableDeclaration` arguments, when compiling ES5 code).

Additionally, since we need those class declarations to be referenced in
other parts of the program, `ngtsc`/`ngcc` had to either repeatedly
check for `ts.isIdentifier(node.name)` or assume there was a `name`
identifier and use `node.name!`. While this assumption happens to be
true in the current implementation, working around type-checking is
error-prone (e.g. the assumption might stop being true in the future).

This commit fixes this by introducing a new type to be used for such
class declarations (`ts.Declaration & {name: ts.Identifier}`) and using
it consistently throughput the code.

Pete Bacon Darwin b48d6e1b13 fix(ivy): ngcc - empower `Esm5ReflectionHost` to analyze `ModuleWithProviders` functions (#29092)
In ESM5 code, static methods appear as property assignments onto the constructor
function. For example:

```
var MyClass = (function() {
  function MyClass () {}
  MyClass.staticMethod = function() {};
  return MyClass;
})();
```

This commit teaches ngcc how to process these forms when searching
for `ModuleWithProviders` functions that need to be updated in the typings
files.
