Tests: Fix CMakeTestAllGenerators generator list

Browse Source 
Since `cmake --help` output now uses `[arch]` placeholders for the VS
generators, this test has been extracting invalid generator names.
Switch to using `cmake -E capabilities` to get a more robust listing of
the generators that does not depend on parsing human-readable help
output.
