Jelle Zijlstra ec86a4e960 [ty] Add Top[] and Bottom[] special forms, replacing top_materialization_of() function (#20054) ...

Part of astral-sh/ty#994

## Summary

Add new special forms to `ty_extensions`, `Top[T]` and `Bottom[T]`.
Remove `ty_extensions.top_materialization` and
`ty_extensions.bottom_materialization`.

## Test Plan

Converted the existing `materialization.md` mdtest to the new syntax.
Added some tests for invalid use of the new special form.
