Add optional Vampir auto-launch integration

[OutlyingWest]

Adds optional Vampir launching functionality. When enabled by a magic command, the kernel will automatically launch Vampir on the generated traces.otf2 file after Score-P instrumented cell execution.

Features

%%enable_vampir_launch_on_scorep_instrumented magic:

Enables Vampir auto-launch after the next Score-P instrumented execution.

%%disable_vampir_launch magic:

Disables Vampir auto-launch.

Works great!
Can you check in the %%enable_vampir_launch_on_scorep_instrumented already whether vampir is on $PATH? If it is not, provide a hint that it has to be added in order to enable the loading feature, e.g. via adding it with %env magic command.

Besides that, please check for consistency in line and cell magics, as discussed.

I added check in the %%enable_vampir_launch_on_scorep_instrumented fcc92dc and changed "not found in PATH" message in 29a7570
