pan/decode: Interpret LOAD_MULTIPLE opcode when decoding a command stream

Browse Source 
This way we can support decoding of descriptors that are passed through
context registers, which we will need for panvk, where the tiler/FB
descriptors come from the VkQueue object, and are passed to command
buffers.

Of course, that means we can only see the latest version of such
indirectly passed data, but that's already the case for most descriptors
that are used several times in a command buffer anyway.
