[.NET 4.x][IL2CPP] MultiCastDelegate is leaking memory in Built projects
To reproduce:
1. Download attached project "LeakTestCase.zip" and open in Unity
2. Open "SampleScene" scene
3. Set Scripting Runtime Version to ".NET 4.6 or .NET 4.x"
4. Set Scripting Backend to "Mono"
5. Build & Run on any platform
6. Observe that the onscreen memory usages stay fixed
7. Set Scripting Backend to "IL2CPP"
8. Build & Run on any platform
Expected results: Like in Mono, the onscreen memory usages stays fixed
Actual results: There is a memory leak in "foo += handler; foo -= handler;" because the memory counter keeps climbing
Notes:
- This issue appears on both Windows and OSX
- This issue reproduces on Android, iOS, and Standalone
- On .NET 3.5 everything works as expected no matter which Scripting Backend is set
Reproduced on Unity 2017.2.3p3, 2017.3.2f1, 2017.4.8f1, 2018.1.9f1, 2018.2.2f1 and 2018.3.0a7

Could you also test this on Nintendo Switch platform? I found memory usage going up when call foo -= handler. It's 2017.4.6f1 with .NET 3.5, Nintendo Switch SDK 5.4.0.
