Pragma for short-circuit evaluation

[phobos2077]

Added support for #pragma sce for convenient enabling of short-circuit evaluation on a per-script basis

Testing methods:

• Looked at int2ssl dump of the script with and without pragma to confirm SCE opcode patterns.
• In-game test of the same script with and without pragma that checks for side effects in procedure that's not called with SCE enabled.

These RPU scripts fail to compile in webassembly and Linux versions, I'm not sure why. Since windows build and my local build (also windows) works without issue with these scripts, I assume it is some OS specific or RPU specific problem. I can't debug that on my system.

Perhaps @roginvs can help with looking into the compile failure?

@phobos2077 I just tried locally using this branch and tests passed. Maybe cache is outdated, let's try first to bump cache version (i.e. just replace v1004 into something else)
