Remove alpha / beta feature available methods 

These are unused and the plan is to move away from having implicit
feature flags for licensed features so we remove them here

### Feature flags for licensed features
If a feature is license-gated, there's no need to add an additional
explicit feature flag check since the flag is checked as part of the
`License.feature_available?` call. Similarly, there's no need to "clean up" a
feature flag once the feature has reached general availability.
The [`Project#feature_available?`](https://gitlab.com/gitlab-org/gitlab/blob/4cc1c62918aa4c31750cb21dfb1a6c3492d71080/app/models/project_feature.rb#L63-68),

......@@ -328,38 +323,11 @@ Due to limitations with `feature_available?`, the YAML definition for `licensed`
flags accepts only `default_enabled: true`. This is under development as per the
[related issue](https://gitlab.com/gitlab-org/gitlab/-/issues/218667).
#### Alpha/beta licensed feature flags
This is relevant when developing the feature using
[several smaller merge requests](https://about.gitlab.com/handbook/values/#make-small-merge-requests), or when the feature is considered to be an
[alpha or beta](https://about.gitlab.com/handbook/product/gitlab-the-product/#alpha-beta-ga), and
should not be available by default.
As an example, if you were to ship the frontend half of a feature without the
backend, you'd want to disable the feature entirely until the backend half is
also ready to be shipped. To make sure this feature is disabled for both
GitLab.com and self-managed instances, you should use the
[`Namespace#alpha_feature_available?`](https://gitlab.com/gitlab-org/gitlab/blob/458749872f4a8f27abe8add930dbb958044cb926/ee/app/models/ee/namespace.rb#L113) or
[`Namespace#beta_feature_available?`](https://gitlab.com/gitlab-org/gitlab/blob/458749872f4a8f27abe8add930dbb958044cb926/ee/app/models/ee/namespace.rb#L100-112)
method, according to our [definitions](https://about.gitlab.com/handbook/product/gitlab-the-product/#alpha-beta-ga). This ensures the feature is disabled unless the feature flag is
_explicitly_ enabled.
If you want a licensed feature to be disabled by default or enabled only for a given gate, you can use a feature flag with a different name. The feature checks would then
look like:
CAUTION: **Caution:**
If `alpha_feature_available?` or `beta_feature_available?` is used, the YAML definition
for the feature flag must use `default_enabled: [false, true]`, because the usage
of the feature flag is undefined. These methods may change, as per the
[related issue](https://gitlab.com/gitlab-org/gitlab/-/issues/218667).
The resulting YAML should be similar to:
```yaml
name: scoped_labels
group: group::memory
type: licensed
# The `default_enabled:` is undefined
# as `feature_available?` uses `default_enabled: true`
# as `beta_feature_available?` uses `default_enabled: false`
default_enabled: [false, true]
```ruby
Feature.enabled?(:licensed_feature_feature_flag, project) && project.feature_available?(:licensed_feature)
```
