`ChronoField` has four fields for hours - HOUR_OF_DAY, HOUR_OF_AMPM, CLOCK_HOUR_OF_DAY and CLOCK_HOUR_OF_AMPM. The Javadoc for HOUR_OF_DAY should be enhanced to refer to CLOCK_HOUR_OF_DAY and vice versa. The same should be done for HOUR_OF_AMPM and CLOCK_HOUR_OF_AMPM.

This change will help users find their way between each pair of fields.

The documentation added to HOUR_OF_DAY will be something like

"<p>
See {@link #CLOCK_HOUR_OF_DAY} for the related field that counts hours from 1 to 24.
"

It would seem wise to also update the documentation of AMPM_OF_DAY to refer to CLOCK_HOUR_OF_AMPM to ensure users can connect their options.

This change does not affect the meaning or intent of the spec, it just adds clarification.

There is also a bug in CLOCK_HOUR_OF_DAY where it refers to "AM/PM" instead of "day".
