devenv: Allow dumping into file and select a format

It is often more useful to generate shell script than dumping to stdout.
It is also important to be able to select the shell format.

Formats currently implemented:
- sh: Basic VAR=prepend_value:$VAR
- export: Same as 'sh', but also export VAR
- vscode: Same as 'sh', but without substitutions because they don't
  seems to work. To be used in launch.json's envFile.
