Forward-merge triggered by push to branch-22.08 that creates a PR to keep branch-22.10 up-to-date. If this PR is unable to be immediately merged due to conflicts, it will remain open for the team to manually merge.

This PR introduces a cudf option to allow user to control the default bitwidth for integer and floating types. The first iteration only plans to provide three options: `None`, 32bit and 64bit. When set as `None`, that means the result dtype will align with what pandas constructs. Otherwise, default to what user specifies.

"Default" implies that it should only affects places that requires type inference, that includes:

- CSV/JSON readers when dtypes are not specified
- cuDF constructors
- Materializing a range index.

This PR is the first demonstration use of `cudf.option`, depending on #11193. Diff will reduce once it's merged.
