[macOS] Builds don't use Burst when generated via "Create Xcode Project"

Package: Burst

-

How to reproduce:
1. Open the attached “StandaloneBurstTest“ project
2. Build the project with “Create Xcode Project”, “Development Build” and “Autoconnect Profiler” enabled
3. Open the “build.xcodeproj” file in the build folder
4. Run the build
5. Open the Editor window (select “Window” → “Analysis” → “Profiler” in the main menu if the Profiler did not open automatically)
6. Click on any frame
7. Observe the length of the PlayerLoop() call

Expected result: The call takes 1-10ms to execute (Burst works)
Actual result: The call takes 15-30ms to execute (Burst doesn’t work)

Reproducible with: 1.8.0-pre.2 (2020.3.40f1, 2021.3.11f1, 2022.1.19f1, 2022.2.0b10), 1.8.0 (2023.1.0a13)

Reproducible on: macOS 12 beta (Apple M1)

Note: Doesn’t reproduce in the Editor or in non-Xcode builds
