## What does this PR do?
An XcodeProject/XcodeWorkspace now knows its own location on disk, which
is important when we start using these types to build PIF.

## Summary by CodeRabbit
* **Improvements**
* Projects and workspaces now retain their associated locations and save
directly to those locations.
* Generated project files preserve the configured project directory
path, helping keep file references consistent when projects are written
or reopened.
* Projects and workspaces can be associated with a new location while
retaining their existing contents.

## What does this PR do?
Improves `xtool dev generate-xcode-project`. Instead of constructing an
XcodeGen project, we directly construct an xcodeproj (with the new
xcproj format) using
[apple/xcode-project-format](https://github.com/apple/xcode-project-format).
For now, we still rely on
[Tuist/XcodeProj](https://github.com/tuist/XcodeProj) to translate it
back into a pbxproj for maximal compatibility, but this is treated as an
implementation detail.
Also adds support for resources and icons in the generated Xcode project
## How was it tested?
- [x] Generated a simple project, opened it, and ran the app
