This moves the JSON evalengine implementation so we can share it more across different components.

Specifically vreplication wants to also use the same JSON parser so it can handle dealing with the MySQL types inside JSON objects better.

It also implements the same parsing for the MySQL binary JSON format and a serialization to using SQL style functions to limit typing loss as much as possible.

There's still two types that cause problems. When using TIMESTAMP or BIT types inside a JSON document it's impossible to create an SQL format compatible with those types since there's no way to create literals for those two types.

Related Issue(s)

This helps with a better fix for #12731 that handles more types correctly.

Hello reviewers! 👋 Please follow this checklist when reviewing this Pull Request.

General

  • Ensure that the Pull Request has a descriptive title.
  • If this is a change that users need to know about, please apply the release notes (needs details) label so that merging is blocked unless the summary release notes document is included.
  • If a test is added or modified, there should be a documentation on top of the test to explain what the expected behavior is what the test does.

If a new flag is being introduced:

  • Is it really necessary to add this flag?
  • Flag names should be clear and intuitive (as far as possible)
  • Help text should be descriptive.
  • Flag names should use dashes (-) as word separators rather than underscores (_).

If a workflow is added or modified:

  • Each item in Jobs should be named in order to mark it as required.
  • If the workflow should be required, the maintainer team should be notified.

Bug fixes

  • There should be at least one unit or end-to-end test.
  • The Pull Request description should include a link to an issue that describes the bug.

Non-trivial changes

  • There should be some code comments as to why things are implemented the way they are.

New/Existing features

  • Should be documented, either by modifying the existing documentation or creating new documentation.
  • New features should have a link to a feature request issue or an RFC that documents the use cases, corner cases and test cases.

Backward compatibility

  • Protobuf changes should be wire-compatible.
  • Changes to _vt tables and RPCs need to be backward compatible.
  • vtctl command output order should be stable and awk-able.
  • RPC changes should be compatible with vitess-operator
  • If a flag is removed, then it should also be removed from VTop, if used there.
