Implemented --show-properties in board details command (#2151)

* Renaming some variables for clarity

* Moved 'build.board' property generation out of legacy package

* Moved unit tests related to build properties out of legacy package

* Removed legacy TargetBoardResolver and refactored unit-tests

* Removed legacy HardwareLoader

* Factored sketch-related build properties creation

* Moved SetupBuildProperties into proper package

* Removed SetCustomBuildProperties from legacy

* Factored --show-properties cli flag parser

* Made 'board ...' command arguments variables local

* Implemented --show-properties in 'board details'

* Fixed integration test
