topology: Add API to set a vendor specific version number

Browse source 
This vendor-specific version number is optional. It will be written to
the 'version' field of each block header of the binary toplogy data file.
The vendor driver can check this number for further processing in kernel.

The topology ABI version number is still stored in the 'abi' field of
block headers.
