RFR: 8263134: HotSpot Style Guide should disallow inheriting constructors [v2]

[Kim Barrett]

> Please review this change to explicitly disallow the use of inheriting
> constructors:
> (http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2008/n2540.htm).
> 
> The C++11/14 specification has a lot of problems. These were addressed in
> C++17 (and as a DR that affects C++11/14):
> (http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2015/p0136r1.html).
> 
> Use of inheriting constructors now runs the risk of encountering those bugs,
> inconsistent behavior between different compilers or compiler versions, and
> behavior changes for future support of C++17.
> 
> This is a modification of the Style Guide, so rough consensus among the
> HotSpot Group members is required to make this change. Only Group members
> should vote for approval (via the github PR), though reasoned objections or
> comments from anyone will be considered. A decision on this proposal will not
> be made before Friday 18-Mar-2022 at 12h00 UTC.
> 
> Since we're piggybacking on github PRs here, please use the PR review process
> to approve (click on Review Changes > Approve), rather than sending a "vote:
> yes" email reply that would be normal for a CFV.
