1. Extended the gdb-remote communication related classes with disk file/directory completion functions; 2. Added two common completion functions RemoteDiskFiles and RemoteDiskDirectories based on the functions above; 3. Added completion for these commands: A. platform get-file <remote-file> <local-file>; B. platform put-file <local-file> <remote-file>; C. platform get-size <remote-file>; D. platform settings -w <remote-dir>; E. platform open file <remote-file>. 4. Added related tests for client and server; 5. Updated docs/lldb-platform-packets.txt. Reviewed By: labath Differential Revision: https://reviews.llvm.org/D85284
