Global timeout should support multi-file analysis

[ericwb]

Is your feature request related to a problem? Please describe.
Currently the global default timeout is only handled on a per-file basis. However, it should be handled per-runtime.

Describe the solution you'd like
To accomplish a per-runtime global state of the default timeout, files for a target need to be treated as a project and Precli needs to understand the entry-point of the program and how files are imported and loaded.
