Add enum features into `@JsonFormat.Feature`

[Anatoly4444]

com.fasterxml.jackson.annotation

I have several enum objects which jackson deserialize and requests failed after third company API updated possible values in this object. And also i don't want to add this Feature for whole project cause this feature could broke logic for another requests.

Jackson has com.fasterxml.jackson.annotation.JsonFormat.Feature which could be added on certain class but for now that does not support READ_UNKNOWN_ENUM_VALUES_AS_NULL and READ_UNKNOWN_ENUM_VALUES_USING_DEFAULT_VALUE. Please add

@cowtowncoder said i should create issue here, not in jackson-annotations

Thank you @Anatoly4444 -- yes, this is slightly better place since support must be added here too; and adding entries in jackson-annotations can be done as part of implementation (filing separate issue only when working on making things work).

[cowtowncoder]

Adding labels to indicate that help would be welcome here, and that I think this is relatively straight-forward to implement.

Merged, to be included in 2.15.0. Thank you for the contribution @Siwach16!
