Add support for -ccs.autoImport

[jhmcksdl]

Hi,

First off thanks for writing and maintaining this action. It's exactly what I've been looking for to automate validation and capture of our firmware builds.

Unfortunately, we're running into a problem where we have several shared dependency projects within the CCS workspace. This action imports one project at a time and then builds that project, so the compiler is not finding these referenced projects.

One thing I noticed when experimenting with this action is that CCS has the ability to auto-import all projects found in the workspace root, using the flag -ccs.autoImport:

NOTE: use the '-ccs.autoImport' argument to automatically import projects found in the workspace root directory.

Would it be possible to add support for this?
