#13123 MaxLength limiting included for Json Columns

[deepthi912]

#13123
Fix:

1. Added code to sanitize the json column to "$SKIPPED$". The way it is in JsonIndex.
2. Exposed Server metric for the sanitized values (numColsLimitedByMaxLength)

There seems to be duplication with the below PR:
#13103
