Hardware support and bugfix update

This update aims to reduce the overall memory usage and improve the efficiency for Intel processors of 12th gen and later.

It also provides workarounds for long-standing bugs in the Intel integrated graphics drivers for these processors. If you experience random flashing colors and graphics corruption, make sure to use windowed mode and double-click anywhere in the game window to reset the graphics subsystem.

The newly added command Shift+Ctrl+Z selects all mechs of the same type(s) as those currently selected, if and only if they were built by the same factories/labs/builders. This is an extension of the original Ctrl+Z command that will select all mechs of the same type(s).
