GH-8613: Add JsonPropertyAccessor type for native (#8614)

Fixes #8613

If `JsonPropertyAccessor` is registered for SpEL, it would be great
to have it working in native images as well.

Since SpEL is fully based on reflection, expose
`JsonPropertyAccessor$ComparableJsonNode` and `JsonPropertyAccessor$ArrayNodeAsList`
reflection hints for their method invocations from SpEL

**Cherry-pick to `6.0.x`**
