Update FedRamp PAT creation to be an Application setting or via API
As part of FedRamp requirements, PAT creation was disabled for FIPs enabled instances using Gitlab::FIPS.enabled
in the MR Disable Personal Access Tokens in FIPS mode (!97299 - merged) The 2FA bypass (& therefore PAT disabling) is a FedRamp requirement and as such not directly needed by FIPs where certain deployments may be running on FIPs node and still need tokens for automation.
The proposal Introduce a FedRAMP-hardened mode separate from... (#384110) suggests to uncouple PAT creation from the flag Gitlab::FIPS.enabled
onto an application setting or via an API.
