Add support for Xcode 16 and synchronized groups

[gui17aume]

This PR aims to support Xcode 16 project files and especially the new file system synchronized groups.

It is based on the work done by @Brett-Best in this other PR: #942 👍

Changes

• Add the new object version 77
• Add types and fields related to file system synchronized groups :

  PBXNativeTarget
+   fileSystemSynchronizedGroups

+ PBXFileSystemSynchronizedRootGroup
+   exceptions
+   explicitFileTypes
+   explicitFolders
+   indentWidth
+   path
+   sourceTree
+   tabWidth
+   usesTabs
+   wrapsLines

+ PBXFileSystemSynchronizedBuildFileExceptionSet
+   additionalCompilerFlagsByRelativePath
+   attributesByRelativePath
+   membershipExceptions
+   platformFiltersByRelativePath
+   privateHeaders
+   publicHeaders
+   target

+ PBXFileSystemSynchronizedGroupBuildPhaseMembershipExceptionSet
+   buildPhase
+   membershipExceptions
+   platformFiltersByRelativePath

  XCBuildConfiguration
+   baseConfigurationReferenceAnchor
+   baseConfigurationReferenceRelativePath

Thank you @Brett-Best and @gui17aume both for contributing this 🙏

I'm going to do some follow up testing & updates for Xcode 16 and then will ship a new release.

is there a reason you have this explicit string here vs what Xcode itself generates here: PBXFileSystemSynchronizedBuildFileExceptionSet

Xcode replaces this string with that when editing the project file, so we're seeing a back-and-forth diff of this comment being edited by both parties.

[Brett-Best]

I checked in Xcode 16.2RC and this string format is what is used on my projects still.

oh I'm on 16.1, let me try 16.2 real quick to verify

[walkingbrad]

hmm Xcode 16.2 RC still reverts this comment:

1. we're calling fastlane increment_version_number_in_xcodeproj, which just does project = Xcodeproj::Project.open, edits a build setting, then does project.save
2. this custom comment then gets added
3. move a package/group/file in Xcode that is tracked in the project file
4. the comment now becomes PBXFileSystemSynchronizedBuildFileExceptionSet

It also happens on our project.

Along with the formatting back and forths:
Xcode 16.2 uses condensed format:

/* Begin PBXFileSystemSynchronizedRootGroup section */
		E12863882D59E53C00CA99E1 /* Sources */ = {isa = PBXFileSystemSynchronizedRootGroup; exceptions = (E12864172D59E53D00CA99E1 /* PBXFileSystemSynchronizedBuildFileExceptionSet */, E12864182D59E53D00CA99E1 /* PBXFileSystemSynchronizedBuildFileExceptionSet */, ); explicitFileTypes = {}; explicitFolders = (); path = Sources; sourceTree = "<group>"; };
		E128641E2D59E56300CA99E1 /* Resources */ = {isa = PBXFileSystemSynchronizedRootGroup; exceptions = (E12864252D59E56300CA99E1 /* PBXFileSystemSynchronizedBuildFileExceptionSet */, ); explicitFileTypes = {}; explicitFolders = (); path = Resources; sourceTree = "<group>"; };
		E128660E2D59E79800CA99E1 /* TestApp */ = {isa = PBXFileSystemSynchronizedRootGroup; explicitFileTypes = {}; explicitFolders = (); path = TestApp; sourceTree = "<group>"; };
		E12866192D59E7B000CA99E1 /* UnitTests */ = {isa = PBXFileSystemSynchronizedRootGroup; explicitFileTypes = {}; explicitFolders = (); path = UnitTests; sourceTree = "<group>"; };
/* End PBXFileSystemSynchronizedRootGroup section */

Xcodeproj 1.27.0 uses petty printed:

/* Begin PBXFileSystemSynchronizedRootGroup section */
		E12863882D59E53C00CA99E1 /* Sources */ = {
			isa = PBXFileSystemSynchronizedRootGroup;
			exceptions = (
				E12864172D59E53D00CA99E1 /* Exceptions for "Sources" folder in "IntentsExtensionUI" target */,
				E12864182D59E53D00CA99E1 /* Exceptions for "Sources" folder in "WidgetExtension" target */,
			);
			explicitFileTypes = {
			};
			explicitFolders = (
			);
			path = Sources;
			sourceTree = "<group>";
		};
		E128641E2D59E56300CA99E1 /* Resources */ = {
			isa = PBXFileSystemSynchronizedRootGroup;
			exceptions = (
				E12864252D59E56300CA99E1 /* Exceptions for "Resources" folder in "IntentsExtensionUI" target */,
			);
			explicitFileTypes = {
			};
			explicitFolders = (
			);
			path = Resources;
			sourceTree = "<group>";
		};
		E128660E2D59E79800CA99E1 /* TestApp */ = {
			isa = PBXFileSystemSynchronizedRootGroup;
			exceptions = (
			);
			explicitFileTypes = {
			};
			explicitFolders = (
			);
			path = TestApp;
			sourceTree = "<group>";
		};
		E12866192D59E7B000CA99E1 /* UnitTests */ = {
			isa = PBXFileSystemSynchronizedRootGroup;
			exceptions = (

			explicitFileTypes = {

			explicitFolders = (
