Add a table comparing RVA and RVB

[rpsene]

This update enhances the documentation by providing a clear and organized comparison of the RVA and RVB extensions, making it easier for developers and stakeholders to understand the differences and requirements.

• Added a new table to the documentation that provides a detailed comparison between the RVA23U64, RVA23S64, RVB23U64, and RVB23S64 extensions.
• Sorted the entries alphabetically and updated the numbering for clarity and consistency.

@kasanovic @aswaterman please, double check each line. I did went thorough rva and and rvb multiple times, but I'm not 100% confident that I captured it precisely.

Can we add another view of this information that just shows the differences between RVA23 and RVB23? I still want this even though they are split into 2 separate OpaVotes.

[aswaterman]

RVA and RVB are really separate beasts, and so linking them together in the form of a table doesn’t make much sense to me. I’ll scan the table for fact-checking purposes, but I won’t be the one to approve the PR.

[james-ball-qualcomm]

I'm asking for another view of the table that omits rows that are the same between RVA23 and RVB23. Make sense?

[james-ball-qualcomm]

I don't care if it gets approved in a pull request. I just want to see the information.

[aswaterman]

The only bugs I spotted in the table are that Zicond and Zcmop are missing.

I don't see the H extension (mandatory in RVA23, expansion option in RVB23) mentioned. Also, when H is present, there are several other extensions like Ssstateen, Shcounterenw, etc. that become mandatory but I don't see those mentioned in the table either.

@james-ball-qualcomm H and its dependencies are on the table.

[james-ball-qualcomm]

I don't see H or its friends in the table sent out by Jeff about an hour ago. Is his table incorrect/incomplete/out-of-date?

@james-ball-qualcomm I shared a complete version before the email was sent. If you check the Google Sheet, it is fully updated.

[james-ball-qualcomm]

I don't see any email from you sharing a complete version before Jeff's email went out. Also, what do you mean the Google Sheet? All I'm aware of is this ASCIIDOC table in this GitHub and then a PDF that Jeff mailed out. Is there also a Google Sheet?

[james-ball-qualcomm]

I'm sending you a meeting request so we can discuss this live and clear it up quickly.
