ref(hybrid-cloud): Require using param when creating transactions or using unguarded_write decorators

[GabeVillalobos]

With the inclusion of our recent changes to transaction validations in PR #52943 and the inclusion of 'using' in all of our transactions/helpers thanks to PRs #53027 and #53004, we should be able to safely remove the ability to specify a transaction without a using keyword arg.

Because this is now mandatory, it should also be safe to remove autorouting, which ended up being incorrect in many testing contexts anyway.

This is a resubmission of PR #53080 which was reverted due to broken load-mocks and a single broken getsentry migration test.
