fix: Issue with parallel pyMechanical instance on linux

[wsharp-ansys]

Summary

Fixes issues seen in workflows where numerous pyMechanical instances are started in parallel at the same time and exceptions or crashes are seen when Mechanical is starting.

Fixes #1653

Changes

-MWSUB_SPACE environment variable added before Mechanical starts. It needs to be a unique alpha-numeric value which will be assigned to each new instance of pyMechanical that starts. This is a mainwin variable that will assign a sub-space of memory for each Mechanical instance started through pyMechanical. It can be disabled through MWSUB_SPACE_OFF=1 variable.
