update javac flags for java 17 (#628)
Previously -Xlint:text-blocks and -Xlint:text-blocks were enabled
conditionally, if the user had at least java 15 or java 16,
respectively. Enable them always.

Add new options so that the warnings list is fully configured:
* -Xlint:module (new in java 17)
* -Xlint:strictfp (new in java 17)

Disable "path" with -Xlint:-path rather than commenting it out, for
consistency.

Disable "missing-explicit-ctor" (new in java 17), as it is unlikely to
succeed right now.

Alphasort the flags and doc how to get the updated list, this makes it
easy to compare and keep up to date.
