Description of change

I've extracted most of the functionality from the UID2 module to a shared file, to allow re-use with the new EUID module.
I've added a new EUID module.
Both modules now prefer local storage - the UID2 module originally preferred cookie storage. No configs need to change - it's all backward-compatible.

Please handle consent more explicitly in both modules; also discuss why euid is different than the uid2 and why a second module is needed?

As an aside, I looked up gvl id 887, that is the prebid gvl id. You shouldnt be using that for uid2, please change that to either ttd or vendorless module; i think the latter is more appropriate.

Or just delete the gvlid from the uid2 module altogether so only euid gets called in europe

I've added consent handling to both modules. I had a few internal discussions about the possibility of using a single module to handle it, but I got strong pushback - they're different ID spaces with potentially different configuration, and different legal handling as well - not all EUID participants will be UID2 participants, and vice versa.

UID2 & EUID Modules: Add support for EUID and prefer localStorage for…
e8c79c3 
… both modules. (prebid#9968)

* Move the UID2 API client to its own file and refactor some of the UID2 module.

* Provide local-storage option in response to complaints that the cookie can grow large enough to cause problems for publishers.

* Extract a storagemanager from the UID2 ID module so that code can be re-used for EUID.

* Further refactoring. Add basic EUID module based on the refactored code. Still needs tests and testing.

* Factor out some shared testing code.

Add EUID module tests.

* Add EUID markdown docs.

Some minor changes.

* Fill out EUID module docs.

* Rename cookie param for EUID.

Fix some docs.

* Some EUID docs tweaks.

Change UID2 module docs to match EUID docs.
Update param to use uid2Cookie instead of uid2ServerCookie (but still fall back to the old value).

* Added a test and fixed a bug that caused the server only cookie config to fail for subsequent page views.

* Added EUID example.

* Update some tests.

* Added lint rule exception - it makes sense in this case.

* Add missing config for updated test.

* Update expected number of Eids in test.

* Remove out-of-date TODOs.

* Update UID2 module to not run if GDPR applies.

Update EUID to check consent.

* Remove EUID from a specific test - it no longer works as that test doesn't provide consent data, and the EUID module requires it.
