Show anonymous and ambiguous params in ISeq disassembly

Previously, in the disasesmbly for ISeqs, there's no way to know if the
anon_rest, anon_kwrest, or ambiguous_param0 flags are set. This commit
extends the names of the rest, kwrest, and lead params to display this
information. They are relevant for the ISeqs' runtime behavior.
