qemu: capabilities: Introduce QEMU_CAPS_MIGRATION_PARAM_BLOCK_BITMAP_MAPPING

Browse Source 
The capability represents qemu's ability to setup mappings for migrating
block dirty bitmaps and is based on presence of the 'transform' property
of the 'block-bitmap-mapping' property of 'migrate-set-parameters' QMP
command.
