add flag for passing ASM path to command line args
add overload to use flag when present to sandbox, cli, cliwpf

Purpose

Attempt to allow integrators to use DynamoSandbox without requiring potentially slow recursive file search on the users system.

If this PR is merged the consequences are:

1. sandbox daily builds will not load on applications which do not have ASM in their root directory - this is the same behavior as 2.3 (even if they are added to the list to search for)
2. These applications will need to use can use a command line flag - -gp to pass the geometryPath to sandbox to have it skip searching and load that directly.

a thought:

to enable the most flexible solution - we can keep the recursive loading but move our tests and other integrators to use the command line flag (or preload option) to avoid searching - for example - we can modify our tests to stop geometry library searching and instead use this same mechanism to load the geometry library from a known a specific location.

This will enable us to keep the slow searching behavior for daily build users but skip it for integrators and tests...

This PR now simply adds the commandLineFlag and keeps the behavior @aparajit-pratap added. So both can used for most flexibility depending on user type.
