Add Jackson 3 support

This commit adds support for Jackson 3 which has the following
major differences with the Jackson 2 one:
 - jackson subpackage instead of jackson2
 - Jackson type prefix instead of Jackson2
 - JsonMapper instead of ObjectMapper
 - For configuration, JsonMapper.Builder instead of ObjectMapper
   since the latter is now immutable
 - Remove custom Jackson 3 support for unmodifiable collections
 - AllowlistTypeResolverBuilder in new a public type in order
   to be used easily with the JsonMapper.Builder API

Jackson 3 changes compared to Jackson 2 are documented on
FasterXML/jackson-future-ideas#72.

This commit does not cover webauthn which is a special case (uses
jackson sub-package for Jackson 2 support) which will be handled in
a distinct commit.
