d9345545 - Reapply "[Dexter] Add DAP support for Dexter, including lldb-dap (#149394)"

Reapply "[Dexter] Add DAP support for Dexter, including lldb-dap (#149394)" This reverts commit e1e312e6af34803d1686d9ce5a441446811f425d. The original patch had some python3.10 syntax, which was incompatible with the python3.8 minimum version in LLVM currently; this reapply brings everything down to 3.8 compatibility. Separately, some incorrect arguments were passed in LLDBDAP._get_launch_params, which have been removed.
