Subject: [PATCH] cmake-gui: Reset generator platform and toolset on configure
 (#15411)

At the start of each configure step we already reset the generator
selection (CMAKE_GENERATOR) to match that loaded for the current
project.  Add missing code to reset the generator platform and toolset
(CMAKE_GENERATOR_PLATFORM and CMAKE_GENERATOR_TOOLSET) also so that they
do not leak across projects.
