revlog: determine sidedata support based on the revlog version
Revlog version "2" support sidedata, previous version does not. So lets make the
initialization simpler.

requirements: no longer drop `generaldelta` requirement with revlogv2
A repository could use a mix of revlogv1 and revlogv2, making the requirements
still necessary. Overall we should move away from the "requirements" file being
used a way to configure the repository and stick to it "what do you need to
access this repository". However this is a wider work for another time.
In addition the logic we just dropped was confusing the `hg debugformat`
command, breaking the upgrade code and inconsistent (eg: `sparse-revlog` is also
implied by `revlogv2`).
Finally, multiple other config option would imply the use of the `revlogv2`
requirements, without drop the `generaldelta` one, leading to more
inconsistency.

config: drop the `format.exp-revlogv2.2` option
It is oddly named and not used at all. The one used by the code is still
`experimental.revlogv2`. So we drop that one option for consistency. We move
associate documentation to the actual option.

revlog: only use the `_indexfp` method for read operation
This will avoid "other" code to not overlook `_writing` usage. We introduces
private method dedicated to writing to make use the right option are always
used.
