  [mlirbc] Add AffineMap serialization support

Add binary bytecode encoding for AffineMapAttr, replacing the textual fallback.
AffineMap is encoded as numDims, numSymbols, numResults, followed by the result
expressions.  Where each expression, AffineExpr, is encoded as a recursive tree
with a VarInt kind tag followed by kind-specific data.
