George Kalpakas 78214e72ea fix(ngcc): avoid warning when reflecting on index signature member (#33198)
Previously, when `ngcc` was reflecting on class members it did not
account for the fact that a member could be of the kind
`IndexSignature`. This can happen, for example, on abstract classes (as
is the case for [JsonCallbackContext][1]).

Trying to reflect on such members (and failing to recognize their kind),
resulted in warnings, such as:
```
Warning: Unknown member type: "[key: string]: (data: any) => void;
```

While these warnings are harmless, they can be confusing and worrisome
for users.

This commit avoids such warnings by detecting class members of the
`IndexSignature` kind and ignoring them.
