Add option to remove Intel-specific JVM arg for compatibility

[Arminias]

Role

I play modded MC and am one of the maintainers of BTW

Suggestion

Add option to remove Intel-specific JVM arg for compatibility (e.g. in the instance's Workaround tab or similar)

Benefit

This will make people on old Intel iGPUs be able to - if they wish so - use other Java than 8 u51. Especially required on old MC versions when needing to use more modern Java.

This suggestion is unique

• I have searched the issue tracker and did not find an issue describing my suggestion, especially not one that has been rejected.

You may use the editor below to elaborate further.

The arg in question is MojangTricksIntelDriversForPerformance_javaw.exe_minecraft.exe.heapdump. Seen here:

Launcher/launcher/minecraft/MinecraftInstance.cpp

Line 337 in bb04cb0

args << QString("-XX:HeapDumpPath=MojangTricksIntelDriversForPerformance_javaw.exe_"

This always gets added on Windows and can't be removed by the user right now.
Removing it can cause varying performance degradation - therefore I suggest adding it in the Workaround tab - though not always significant.
This will make affected users be able to use other Java versions than 8 u51 when enabled and make them able to launch old MC versions on modern Java without any problems.
(Regarding 8 u51, see this MultiMC wiki entry: https://github.com/MultiMC/Launcher/wiki/Unsupported-Intel-GPUs)

I tested this on a custom build of MultiMC I did myself that removed this arg and other versions than 8 u51 started working without any issues.
