GH4055: Add task skip reason to task summary output

[gep13]

Via a new setting, --Settings_UseSpectreConsoleForConsoleOutput, it is now possible to output the task headers, and task summary using Spectre.Console. This allows for the easy addition of a new column in the task summary, which includes information about why any given task has been skipped.

The old CakeReportPrinter is still in play, but some implementation has been moved from within the DefaultExecutionStrategy to the reporter class. Depending on the setting mentioned above, either the Spectre.Console version of the reporter will be added to the IoC container, or the old version will be in place.

Fixes #4055
