OpenEXR, OpenColorIO, OpenImageIO all depend on this. IMath used to be part of OpenEXR but is its own library in the latest versions, which OpenEXR depends on. Signed-off-by: Nicholas Lawson <70027408+nick-l-o3de@users.noreply.github.com>

IMath used to be part of OpenEXR but is its own library in the latest versions, which OpenEXR depends on.
Note: This also adds the new functionality to the pull_and_build_from_git.py script to allow
file overcopy, and custom cmake file generation to support configs, as well as custom ENV vars being set inside the build environment.
