The BTreeSet and BTreeMap gdb pretty-printers did not take the node structure into account, and consequently only worked for shallow sets. This fixes the problem by iterating over child nodes when needed. This patch avoids the current approach of implementing some of the value manipulations in debugger-indepdendent code. This was done for convenience: a type lookup was needed for the first time, and there currently are no lldb formatters for these types. Closes #55771
