Adds scim settings, scim settings integration tests and generated mocks

[skj-skj]

Description

This PR adds site-level SCIM settings support via a new admin_setting_scim.go resource and the AdminSettings.SCIM interface. It also includes integration tests, supporting helper functions, and generated mocks for the new resource.

Reviewer Note

generateSCIMToken currently performs a direct API call to generate the SCIM token, as go-tfe does not yet expose a SCIM token resource. This will be cleaned up in a subsequent PR that introduces first-class SCIM token support.

Testing plan

1. Added Integration test for Read, Update and Delete for SCIM Settings
