RFR: 8265399: Update to Visual Studio 2019 version 16.9.3 [v2]

[Kevin Rushforth]

> This patch updates the compiler to Visual Studio 2019 version 16.9.3 on Windows, in order to match JDK 17 -- see [JDK-8265371](https://bugs.openjdk.java.net/browse/JDK-8265371).
> 
> I ran a full build and test, including media and WebKit.
> 
> NOTE: I also have PR #481 out for review to update the Linux gcc compiler. I intend to integrate that one first, at which time I will need to merge `master` into this branch to resolve a trivial merge conflict (the changes are on adjacent lines).

Kevin Rushforth has updated the pull request with a new target base due to a merge or a rebase. The pull request now contains two commits:

 - Merge 'master' into '8265399-vs2019-16.9.3'
 - 8265399: Update to Visual Studio 2019 version 16.9.3
