core: Add ruff rules FBT001 and FBT002 (#30695)

Add ruff rules
[FBT001](https://docs.astral.sh/ruff/rules/boolean-type-hint-positional-argument/)
and
[FBT002](https://docs.astral.sh/ruff/rules/boolean-default-value-positional-argument/).
Mostly `noqa`s to not introduce breaking changes and possible
non-breaking fixes have already been done in a [previous
PR](https://github.com/langchain-ai/langchain/pull/29424).
These rules will prevent new violations to happen.
