Move the :libraries:wellknown logic into enterprise modules (#7429)

* Extract `IsEnterpriseBuild` use case

Having it inside `EnterpriseService` made having DI cycles with the `BuildMeta` provider too easy

* Rename `EnterpriseService.defaultHomeserverList()` to `homeserverAllowList()`

This seems more aligned with the way this list works

* Move most of the logic from `:libraries:wellknown` to `:enterprise:feature:enterprise`, both `shared` and `impl` modules

Ideally I would have added everything into `impl`, but some of the classes needed to be shared between the different `:enterprise:features` modules, and those are in the `shared` module, lacking a better name/strategy

* Add `EnterpriseService.isElementProEnforced`

With this, we don't need to provide the `RemoteEnterpriseConfig` anymore to any consumers, everything goes through `EnterpriseService` or other providers

* Remove `EnterpriseService.overriddenElementWellKnown`

This leaks the remote enterprise config/element well known contents to the app in a public interface.

* Create `CustomMapTilerConfigProvider` to avoid leaking the `RemoteEnterpriseConfig` in public APIs

This commit also starts moving some of the well-known related values to the enterprise modules

* Add missing docs to `EnterpriseService` and `SessionEnterpriseService`

* Fix tests

* Fix lint issues

* Bump enterprise module
