Improve usage of @jvms tags in class file API

In various parts of the class file api where the `@jvms` tag is used as an inline tag, it is used in an idiom like:

"... as defined in {@jvms 4.7.20.2}"

This renders as

"... as defined in 4.7.20.2."

where "4.7.20.2" is a link to a the corresponding section. Elsewhere in core libs, the pattern used is

"... as defined in JVMS {@jvms 4.7.20.2}"

which renders as

"... as defined in JVMS 4.7.20.2."

which IMO is much clearer to reader.
