Windows NSIS builds fail with MAXBUFFER error for very large archives

[dpgraham]

Version: 20.38.5
Target: Windows NSIS

Attempts to build Windows NSIS with command build --win are failing with ERR_CHILD_PROCESS_STDIO_MAXBUFFER error.

Logs: https://gist.github.com/dpgraham/17e9758c29269d166bf8e5f9994b9e57

• The problem is that 7zip logs the contents of the archive, and our archive is HUGE, which causes the ERR_CHILD_PROCESS_STDIO_MAXBUFFER error

• I was able to fix it locally by changing the hardcoded maxBuffer from 10 * 1024 * 1024 to 1000 * 1024 * 1024 at this line

• I suspect that the problem is happening in NsisTarget.ts where it's calling exec <7zipBinary> -l <.7z>. If the logs were suppressed on this line, that would probably fix the problem too.

Possible fixes are

1. Bump up the maxBuffer size
2. Suppress logging for call to the 7zip binary
3. See if there's a flag to add to the call to the 7zip binary that prevents it from logging archive contents
4. Make maxBuffer size configurable
