ci(build): replace Chocolatey MFC install with Visual Studio bootstrapper

Switches the workflow from Chocolatey to the official Visual Studio Build Tools
bootstrapper to install VCTools and MFC components. This avoids community feed
timeouts, removes nondeterministic 0/0 install failures, and installs the toolchain
into C:\BuildTools for isolation from the preinstalled VS instance.
