Fixes #31797

I finally had time to work on this.

I've implemented it so that, when an adjacent dSYM exist and its uuid match that of the current binary, we load its DWARF and use that for all getDwarfForAddress requests.
All of this is done eagerly at MachOFile.load for simplicity rather than later and lazier. Happy to change that to whatever you think is best.

This implementation is quite minimal and makes dSYM support "best-effort" as in, it treats dSYM parsing error as non-fatal and fallbacks using the current stabs/ofiles mechanism.
