[lldb/Commands] Add support to auto-completion for user commands
This patch should allow the user to set specific auto-completion type for their custom commands. To do so, we had to hoist the `CompletionType` enum so the user can access it and add a new completion type flag to the CommandScriptAdd Command Object. So now, the user can specify which completion type will be used with their custom command, when they register it. This also makes the `crashlog` custom commands use disk-file completion type, to browse through the user file system and load the report. Differential Revision: https://reviews.llvm.org/D152011 Signed-off-by: Med Ismail Bennani <[email protected]>
