feat(sdk-trace-base)!: drop ability to auto-instantiate propagators beyond defaults

[pichlermarc]

Which problem is this PR solving?

It is currently confusing which packages implement auto-configure and to which extent. We currently auto-instantiated propagators based on environment variables in sdk-trace-base.

This PR makes it so that only the default propagators get registered when *TracerProvider#register() is called.
The auto-configuration code moves to @opentelemetry/sdk-node. Dependencies to other propagators are removed from @opentelemetry/sdk-trace-node. #4672

I will follow up later on removing BasicTracerProvider#register() (tracked in #5290)

Fixes #4672
Refs #5290

Type of change

• Breaking change (fix or feature that would cause existing functionality to not work as expected)

Removing/replacing this will likely take 3 more PRs to make the change somewhat reviewable

• introducing an alternative function called registerTraceSdkGlobals() or similar
• migrating to that new alternative function
• dropping register()

But this PR is still an improvement for now as we can shed the imports of non-default propagators/context managers.

LGTM. Just a few nits.
