1. changefeedccl: Rename and remove CDC functions …

   This PR renames and removes CDC specific functions,
   while maintaining backward compatability.
   
   * `cdc_is_delete()` function removed.  It is replaced
     with `event_op()` function which returns a string describing
     the type of event.  If the changefeed is running with `diff`
     option, then this function returns `insert`, `update`, or
     `delete`.  If changefeed is running without the `diff` option,
     we can't tell an update from insert, so this function returns
     `upsert` or `delete`.
   * `cdc_mvcc_timestamp()` function removed.  This information
     can be accessed via cockroach standard system column
     `crdb_internal_mvcc_timestamp`.  The same timestamp column
     is available in the previous row state
     `(cdc_prev).crdb_internal_mvcc_timestamp`
   * `cdc_updated_timestamp()` function renamed as
     `event_schema_timestamp()`
   
   Fixes cockroachdb#92482
   Epic: CRDB-17161
   
   Release note (enterprise change): Deprecate and replace some of the
   changefeed specific functions made available in preview mode in 22.2
   release.   While these functions are deprecated, old changefeed
   transformations should continue to function properly.
   Customers are encouraged to closely monitor their changefeeds
   created during upgrade.  While effort was made to maintain backward
   compatability, the updated changefeed transformation may produce
   slightly different output (different column names, etc).
