8225377: type annotations are not visible to javac plugins across compilation boundaries

[cushon]

JDK-8341779 is a redo of the backport of JDK-8323093, see also discussion in CSR 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 for 21u, a future backport will disable this logic for 17u by default, and optionally allow the fix to be enabled with -XDaddTypeAnnotationsToSymbol.
