ProjectExplorer: Create a ToolRunSupport base class

This is meant to be a base for tool-specific additions to the
target-specific RunControls providing a common base and convenience
interface for the various *{Debug,Analyze,*}Support classes.

Code in the current support classes in intended to be split
in bits suitable to be handled by the target run controls
and in target-independent bits in the pure tool implementation,
making the ToolRunSupport derived instances as slim as possible.
