[OE-core] [OE-Core][master][PATCH] standard.py: Provide an additional option for devtool reset

[Sai Hari Chandana Kalluri]

The devtool reset command cleans the sysroot for a recipe in workspace.
It also removes the append file but leaves the source code as in
workspace. The source is not cleaned intentionally and the user has to
manually remove it before calling devtool modify again.

Provide the user with an option to remove the source code from workspace
by adding a flag to the devtool reset command. The --rm-source option for
the devtool reset command will also clean the source code from the
workspace along with the sysroot and the append file.
Ex: devtool reset --rm-source zip or devtool reset -r zip
