gh-108278: Deprecate passing the first param of sqlite3.Connection callback APIs by keyword (#108632)

Deprecate passing the callback callable by keyword for the following
sqlite3.Connection APIs:

- set_authorizer(authorizer_callback)
- set_progress_handler(progress_handler, ...)
- set_trace_callback(trace_callback)

The affected parameters will become positional-only in Python 3.15.
