Reintroduced json_extract to generate canonicalized output (prestodb#24879)

## Description
The original pull request
[prestodb#24614](prestodb#24614) incorrectly
compares canonicalizedJsonExtract and legacyJsonCast in the equals
function of an object. This issue can be seen in the code
[here](https://github.com/prestodb/presto/pull/24614/files#diff-e921c5d186f9d5daa836bc7330f52caf8c1b84d19cf42288d5a8a7c9a6d2a5d5R156).

As a result, whenever a SQL function requires caching, the cache is
never hit, leading to the creation of new SQL function objects
repeatedly. This behavior eventually causes an OOM error in the JVM
metaspace. and eventually this error led to UER SEV.

After the problematic comparison was updated and tested through shadow
cluster by @rschlussel , we are confident that the issue has been
resolved in this PR. Therefore, we plan to bring back the json
canonicalized extract


## Motivation and Context
Reintroduced json_extract to generate canonicalized output

Reuse JoinType in IndexJoinNode

Reuse JoinType instead of creating IndexJoinNode's own. JoinType is

JoinType would cause naming conflict.
