Subject: [PATCH] Add stopAllThreadsOnSuspend and steppingResumesAllThreads to
 launch.json schema

Both options are honoured by debugpy (read in _set_debug_options for
launch and attach sessions, each defaulting to true) but were missing
from the debugpy launch/attach configuration schema, so VS Code
flagged them as unknown properties in launch.json.

Add both boolean options (default true) with documentation to the
launch and attach schemas in package.json, and declare them on
ICommonDebugArguments so they are typed for both request types.

Fixes #1133
