[YSQL] Update `IndexAMProperty` API to be in sync with YB additions to `IndexAmRoutine`

[tanujnay112]

Jira Link: DB-11164

Description

We have added a few interface methods to IndexAMRoutine in access/amapi.h. However, this comment says that property additions to this struct must alos be reflected in the "property API". This would allow the PG functions pg_indexam_has_property, pg_index_has_property and pg_index_column_has_property to access these new properties.

This issue tracks this sync-up that needs to be done between the two structures as the linked comment suggests.

Hello,
Is this issue still of interest ?

Hi! I'm working on this issue. I've implemented the sync between IndexAMProperty API and YB additions to IndexAmRoutine and created a branch fix/indexam-property-api-sync.

Should I create a pull request for review?
