Add standard osgi.serviceloader OSGi metadata for provided services

[chrisr3]

Add OSGi metadata so that an OSGi framework can consume this bundle's SPI services.

The standard service loader mediator is Apache Aries SPI-Fly.

Excellent, thank you!

Before merging, I just need one thing: CLA, from:

https://github.com/FasterXML/jackson/blob/master/contributor-agreement.pdf

that is, unless you have already sent one -- apologies if so (and if so LMK and I'll dig it up).
If you do need to send one, the usual way is to print it, fill & sign, scan/photo, email to info at fasterxml dot com.

Since you have contributions for both Woodstox and Jackson, it'd make sense to list those separately on two lines for Project. This only needs to be submitted once and works for all contributions.

Once this is done, I'll be happy to merge this for Woodstox 6.3.0 (and probably go ahead and release it) & similarly for Jackson PR.

Thanks, I just need to ask our Legal team to review the CLA first.

@chrisr3 If it's part of regular job, yes. There is also CCLA if that's easier; but individual one is more common (whether for personal or work-related contributions).

I have just emailed the signed CLA to info@fasterxml.com.

Included, released as 6.3.0 (hopefully with more useful metadata now :) ).
