[iOS] Fix iOS export with manually specified signing/provisioning data.

[bruvzg]

Seems like Xcode now defaults to the Automatic signing mode unless Manual signing style is set in the project.

• For automatic signing mode only App Store Team ID should be set, the rest can be left blank.
• For manual signing, Provisioning Profile UUID and Codesign Identity should be also set.

Note: I do not have an Apple Developer account, and can't fully test it, but it seems to be working at least for the ad-hoc mode.

Fixes #57195

FYI, I still see "iPhone Developer" and "iPhone Distribution" when I'm trying to get the "Automatic" provisioning style. Worked around with this as a wrapper for xcodebuild (changed PATH before invoking Godot)

#!/bin/bash
PBX=out/ios/MyAmazingGame.xcodeproj/project.pbxproj

# undo godot's v3.5.2 wrong take here

sed 's/iPhone Developer//' < $PBX > $PBX.fix
mv $PBX.fix $PBX
sed 's/iPhone Distribution//' < $PBX > $PBX.fix
mv $PBX.fix $PBX

exec /usr/bin/xcodebuild "$@"
