Before RC we need to update the man pages in the repo from their Markdown
sources. All pages at a minimum have 23-ea replaced with 23, and publication
year set to 2024 if needed.
This also picks up the unpublished changes to java.1 from:

Looks good and simple.

Marked as reviewed by liach (Reviewer).
`TypeAnnotation` is not an annotation, as it should not be used in places like
`AnnotationValue.ofAnnotation`. Thus it's remodeled to contain an annotation at
a given location instead of to be an annotation.
Depends on #20205.

`BufferedMethodBuilder` accepts a static flag and passes it to the
`CodeBuilder` it creates; yet it does not prevent static flag tampering like
`DirectMethodBuilder` does. This patch makes their behaviors consistent.
Note that the throwing of IAE is provisional; it is open to discussion later.
