Adds metadata classes for Reindex and UpdateByQuery contexts. For Reindex metadata: * _index can't be null * _id, _routing and _version are writable and nullable * _now is read-only * op is read-write must be 'noop', 'index' or 'delete' Reindex metadata keeps the originx value for _index, _id, _routing and _version so that `Reindexer` can see if they've changed. If _version is null in the ctx map, or, equivalently, the augmentation `setVersionToInternal()` was called by the script, `Reindexer` sets document versioning to internal. If `_version` is `null` in the ctx map, `getVersion` returns `Long.MIN_VALUE`. For UpdateByQuery metadata: * _index, _id, _version, _routing are all read-only * _routing is also nullable * _now is read-only * op is read-write and one of 'index', 'noop', 'delete' Closes: elastic#86472

@stu-elastic Did a first pass. Looks pretty good. Given that I'm still getting up to speed a bit here, I would've had an easier time if FieldProperty refactorings was a separate PR.
Also please take a look to see if additional validation of source wrapper is indeed a bug fix because if so that will need to be a separate PR. I made a comment in AbstractAsyncBulkByScollAction about this.

Would you please add a comment here on what this particular INDEX represents. I believe it's the op, right?

Please move this above requestFromOp just to follow the same pattern as execute.

Adds metadata classes for Reindex and UpdateByQuery contexts.
For Reindex metadata:
Reindex metadata keeps the originx value for _index, _id, _routing and _version
so that
Reindexercan see if they've changed.If _version is null in the ctx map, or, equivalently, the augmentation
setVersionToInternal()was called by the script,Reindexersets documentversioning to internal. If
_versionisnullin the ctx map,getVersionreturns
Long.MIN_VALUE.For UpdateByQuery metadata:
Closes: #86472
