[lldb] Pass address expression command args through FixAnyAddress (#147011) Commands that take an address expression/address through the OptionArgParser::ToAddress method, which has filtered this user-specified address through one of the Process Fix methods to clear non-addressable bits (MTE, PAC, top byte ignore, etc). We don't know what class of address this is, IMEM or DMEM, but this method is passing the addresses through Process::FixCodeAddress, and on at least one target, FixCodeAddress clears low bits which are invalid for instructions. Correct this to use FixAnyAddress, which doesn't make alignment assumptions. The actual issue found was by people debugging on a 32-bit ARM Cortex-M part, who tried to do a memory read from an odd address, and lldb returned results starting at the next lower even address. rdar://154885727
