Eugene Yurtsev bb12184551 Internal code deprecation API (#8763) ...

Proposal for an internal API to deprecate LangChain code.

This PR is heavily based on:
https://github.com/matplotlib/matplotlib/blob/main/lib/matplotlib/_api/deprecation.py

This PR only includes deprecation functionality (no renaming etc.). 
Additional functionality can be added on a need basis (e.g., renaming
parameters), but best to roll out as an MVP to test this
out.

DeprecationWarnings are ignored by default. We can change the policy for
the deprecation warnings, but we'll need to make sure we're not creating
noise for users due to internal code invoking deprecated functionality.
