Project fails to build when the SQLite Amalgamation files are included in the project.

In 4.20, it is no longer possible to add the SQLite Almagamation files to a project. Attempting to build a project with these files added results in the build failing due to numerous errors about preprocessir macros in the SQLite files not being defined.

REGRESSION:
Yes. This worked successfully in 4.19.

1. Download the SQLite Amalgamation code (can be found [Link Removed]).
2. Create a new Basic Code project.
3. Copy the sqlite3.c, sqlite3.h, and sqlite3ext.h files from the SQLite Amalgamation into the <Project>/Source/<Project>/ directory.
4. Right-click on the .uproject file and generate project files.
5. Open the project in Visual Studio.
6. Build the project.

RESULT:
The build fails with multiple errors about various preprocessor macros in the SQLite files not being defined.

EXPECTED:
The build completes successfully.
