* More improvements to GDBStub - Debugging of threads should work correctly with source and assembly level stepping and modifying registers and memory, meaning threads and callstacks are fully clickable in VS. - List of modules is available to the client, with assumption that .nro and .nso are backed up by an .elf with symbols, while deconstructed ROMs keep N names. - Initial support for floating point registers. * Tidy up as requested in PR feedback * Tidy up as requested in PR feedback
