feat(effect): Use options in buildEffectLayer without overriding (#19794)

To not mess with `@sentry/core` while adding the new SDK this, the
options are directly moved into the Effect SDK. The main reason why this
is now moved is that mutating the options could lead to other issues,
and this is why I want to keep this in a separate and smaller PR.
