cache: add win32-background-launcher to the cached binaries

on a released crc version the win32-background-laucher will be installed
in the install location of crc by the msi, but while using a non
installer version this'll help to download the win32-background-launcher
binary by running `crc setup`

this is also helpful for testing different versions of the background
launcher during development
