browser.tabs.remote.enforceRemoteTypeRestrictions (defined in modules/libpref/init/all.js, overridden in browser/app/profile/firefox.js) has no remaining reader.

Found by a static analysis of preference usage across mozilla-central: extract every defined pref, then scan the whole tree for each pref's name, its generated StaticPrefs::<id>() / Rust accessor identifier, set_spidermonkey_pref plumbing, and dynamic name-assembly patterns (macro ## paste, adjacent string literals, prefix + leaf concatenation, GetChildList enumeration). Static analysis cannot see access from add-ons or other external consumers, so please confirm before landing

Turning this into a good first bug to help a newcomer learn the workflow.

To verify the fix:

• Confirm the pref has no remaining users by searching for browser.tabs.remote.enforceRemoteTypeRestrictions on https://searchfox.org (only the definition should match).
• Build the tree to make sure nothing breaks:
  ./mach build
