[no-useless-spread] Handle more cases for toSorted (and the likes)

[boris-petrov]

no-useless-spread already handles cases like [...foo.toSorted()] which is awesome! However, it would be nice to also handle [...foo].toSorted() and [...foo].sort(), both of which can be replaced with foo.toSorted().

P.S. Similar work was done in this PR.

[...foo].toSorted()

is not safe to fix, since foo can be other types like string, Set..

Or even can't be reported.

[fisker]

[...foo].sort()

Should definitely go into a new rule like prefer-array-to-sorted.

[abrahamguo]

Wouldn't this suffer from the same problem — foo could still be a string, Set, etc. — and so [...foo].sort() cannot be reported either?

[fisker]

I think it's reasonable to make a generic rule just to forbid .sort() except expression statements.
