qemuBuildFloppyCommandLineControllerOptionsExplicit: Generate via JSON

Browse Source 
QEMU declares the bootindex types as:

  bootindexA=<int32>
  bootindexB=<int32>

The driveA/driveB parameters were deprecated and removed in qemu-6.0.
We'll keep them for compatibility, but they are not used with -blockdev.
