refactor!: Consistent app template/Xcode project name

[dpogue]

Platforms affected

iOS

Motivation and Context

Currently, the generated Xcode project uses the application name for both the project and the target name. This means that file paths in generated projects are not consistent and we have to do regex-based token replacements during project creation. It also makes modifying the template project a pain because opening the template project directly in Xcode causes a bunch of those tokens to break.

The deeper problem is that some tooling (notably Cocoapods) struggles with project and target names with non-ASCII characters.

Possibly closes GH-664.
Mostly closes GH-717 (still impacted by CocoaPods/CocoaPods#7546).
Possibly closes GH-764.
Probably closes GH-793.
Closes GH-795.
Closes GH-826 (due to not needing to do dynamic Info.plist lookups).
Closes GH-955.
Possibly closes GH-1049.
Closes GH-1150.
Closes GH-1289.
Closes GH-1464.

Description

Remaining work:

• Set the PRODUCT_NAME to the config.xml name value so that the resulting app/ipa file has the expected name
• See if we can set PRODUCT_BUNDLE_IDENTIFIER in a better way at create-time to avoid token replacement
• Test with Cocoapods to make sure they still work as expected
• Test with Cocoapods and non-ASCII project names to ensure everything works
• Add a validation check for App.xcodeproj to guard against outdated project files

Will handle as a follow-up PR:

• Test with feat: Support finding an unprefixed Info.plist file cordova-common#212 to see if we can rename App-Info.plist to just Info.plist

Testing

All unit tests pass.
Tested manually with mobilespec.
Tested manually installing onesignal-cordova-plugin in a project with both ASCII and non-ASCII names (ref GH-1289)
Tested manually installing cc.fovea.cordova.openwith in a project and confirmed it built (ref GH-955)
