Mason Daugherty 992c613b51 fix(openai): source LLM context size from model profiles (#37489 )

`BaseOpenAI.modelname_to_contextsize` now reads `max_input_tokens` from
the partner's model profile registry instead of a hand-maintained dict,
with a `@deprecated(since="1.2", removal="2.0")` marker steering callers
at the profile directly. The legacy mapping is trimmed to models that
have no profile (completion-only and dated chat variants) so existing
lookups keep working.
