RDMA/uverbs: Use a linear list to describe the compiled-in uapi
The 'tree' data structure is very hard to build at compile time, and this makes it very limited. The new radix tree based compiler can handle a more complex input language that does not require the compiler to perfectly group everything into a neat tree structure. Instead use a simple list to describe to input, where the list elements can be of various different 'opcodes' instructing the radix compiler what to do. Start out with opcodes chaining to other definition lists and chaining to the existing 'tree' definition. Replace the very top level of the 'object tree' with this list type and get rid of struct uverbs_object_tree_def and DECLARE_UVERBS_OBJECT_TREE.
