topology: utils: add DECLARE_SOF_RT_UUID() helper 

Add a helper DECLARE_SOF_RT_UUID() to generate the 16 Bytes UUID string.

The input string in this format (copied from the FW source directly):
DECLARE_SOF_RT_UUID(name, uuid_macro, a, b, c,
		 d0, d1, d2, d3, d4, d5, d6, d7);

The output string should be in this format:
a6a7:a4a5:a2a3:a0a1:b2b3:b0b1:c2c3:c0c1:d00d01:d10d11:d20d21:d30d31:
d40d41:d50d51:d60d61:d70d71

e.g. for demux component, the macro usage is:
DECLARE_SOF_RT_UUID("demux", demux_uuid, 0xc4b26868, 0x1430, 0x470e,
		 0xa0, 0x89, 0x15, 0xd1, 0xc7, 0x7f, 0x85, 0x1a);

while the output will be:
68:68:b2:c4:30:14:0e:47:a0:89:15:d1:c7:7f:85:1a
