Add constructor accepting `JsonMapperConfigurator` to `Jackson(Jaxb)JsonProvider`

[jolarsen]

Hi,
I came across this when working on a jackson3-module for Jersey and adapting module-filtering to the Mapper-builder-pattern - more specifically the mappers created within MapperConfiguratorBase (defaultMapper...)

• MapperConfiguratorBase have some abstract methods (mapperBuilder + Helper methods for sub-classes) that look suitable
• My thought was to extend JsonMapperConfigurator, implement mapperBuilder or _builderWithConfiguration, and then extend JacksonJsonProvider and provide my MapperConfigurator. Looks cleaner than other options.
• But JacksonJsonProvider / JacksonJaxbJsonProvider have no constructors that accept a custom MapperConfigurator - it only creates one.

Would adding constructors accepting custom MapperConfigurators be OK, or are there other considerations here?
If OK, I could make a quick PR adding such constructors to all 5 modules.

@jolarsen It has been a while since worked on this part of Jackson, so I may be missing something but from your description I don't see immediate concerns. So PR would be welcome as the starting point.

I made PR #227. One question - what are your thoughts on moving from javax.ws.rs-api to jakarta.ws.rs-api for 3.x ?

@jolarsen There is separate repo for Jakarta variant -- https://github.com/FasterXML/jackson-jakarta-rs-providers/ -- independent of Jackson version (i.e. both repos have Jackson 2.x and 3.x support).
