[TIMOB-23212] Adding or removing font assets should force a full rebuild

We automatically add OTF and TTF files to the Info.plist: https://github.com/appcelerator/titanium_mobile/blob/6fa557a07dc723c135704bc86810468900bd381b/iphone/cli/commands/_build.js#L3565-L3588 However, adding or removing a OTF or TTF file does not trigger a full rebuild. So you need to manually clean the build before you can use the font in the app. The CLI should automatically do a full rebuild when an OTF or TTF file has been added/removed.
