BuildReportSummary.json lists Il2CPP and other inactive options when performing a build on Mono

How to reproduce:

1. Create new 3D project and open it
2. Locate Edit > Project Settings > Player > Other Settings > Configuration
3. Set “Scripting Backend” to “Mono”
4. Go to File > Build Profiles > select Windows platform
5. Build with Development Build turned on
6. Open <project>\Library\BuildHistory\<timestamp>\BuildReportSummary.json
7. Observe "BuildOptions" array

Actual result: Summary lists five zero-valued members, falsely reporting Il2CPP for a Mono build
Expected result: Array lists only the actually-set options

Reproducible with: 6000.6.0a1, 6000.6.0b10, 6000.7.0a5
Could not test with: 6000.0.82f1, 6000.3.23f1, 6000.5.10f1 (Build History feature not present until 6000.6.0a1)

Reproducible on: Windows 11 (25H2)
Not reproducible on: No other environments tested

Note: Not backend-specific - an IL2CPP build lists the same inactive members
