ShaderGUI.ValidateMaterial is called inconsistently
Reproduction steps:
1. Open the attached "repro_IN-55375.zip" project
2. Open the "Test" Scene
3. Build the project ("File > Build And Run")
4. Once the build completes, observe a red sphere in the Player - this means that "ValidateMaterial" was not called during the build process
5. Exit the Player
6. Open either the Scene or the Game view and notice (in the Console) that "ValidateMaterial" is called
7. Build the project
8. Notice that, while the project is building, "ValidateMaterial" is called again
9. Once the build completes, observe a green sphere in the Player
Expected result: "ValidateMaterial" is always called for every Material before being written to a build
Actual result: "ValidateMaterial" is only called if Material is visible at the time of a build
Reproduced with: 2021.3.31f1, 2022.3.10f1, 2023.1.16f1, 2023.2.0b12, 2023.3.0a8
Reproduced on: Windows 10 (22H2)
Not reproduced on: No other environments tested
Notes:
* Reproducible in the Player
* If you invert the changes done to the "MaleBody_Test" material, open the "Instantiated" Scene, and enter the Play Mode, the "ValidateMaterial" is not called and the red sphere is shown

Resolution Note:
After much internal deliberation and investigation, we have decided not to fix this issue, since the fix would break a lot of existing projects.
As a compromise, a custom fix has been provided to the customer. We will properly address this issue in future versions of the engine.
