This adds the combined registration (group and project creation
in one page) to the trial registration flow.

Changelog: changed

This adds an experiment for requiring credit card validation
before creating a new group when signing up.

Changelog: added

When new users sign up on GitLab.com, present the option
to verify their credit card in order to enable free pipeline
minutes.

Assign `setup_for_company` to namespaces in the registration flow. This
attribute is assigned to User records in the registration flow and we
also want it on Namespace's created in the reg flow.

Changelog: changed
MR: https://gitlab.com/gitlab-org/gitlab/-/merge_requests/73594
EE: true

Because the combined_registration experiment doesn't have a field for
namespace path, it's hard to validate before the user submits using FE
validation. So here I'm suggesting a path name in case the user does
something wild like uses only an emoji for the group name.

The jobs_to_be_done is being promoted, it asks the user when signing up
what the objective of registering is.

Changelog: added

This experiment combines the group and project pages together to see if
we can increase the success rate of the "first mile".
