[jdk17u-dev] RFR: 8341779: [REDO BACKPORT] type annotations are not visible to javac plugins across compilation boundaries (JDK-8225377) [v2]

[Liam Miller-Cushon]

> [JDK-8341779](https://bugs.openjdk.org/browse/JDK-8341779) is a redo of the backport of [JDK-8323093](https://bugs.openjdk.org/browse/JDK-8323093), see also discussion in CSR [JDK-8346471](https://bugs.openjdk.org/browse/JDK-8346471).
> 
> JDK-8341779 was backported to JDK 21u and released in 21.0.8, as discussed in the CSR this PR proposes integrating it into a future 17u release now that 21.0.8 has been released.
> 
> Similar to [JDK-8360406](https://bugs.openjdk.org/browse/JDK-8360406) for 21u, a future backport will disable this logic for 17u by default, and optionally allow the fix to be enabled with `-XDaddTypeAnnotationsToSymbol`.
