Ability to write all output from any IPM shell command directly to a file in addition to the current device

## Describe the problem
When using IPM shell commands with CPF merge, CPF merge does not provide the current device write outputs in a meaningful manner so it makes sense to persist all output to the current device in a log file _in addition_ to the terminal. This feature request is a continuation of issue #1186 which allowed ShellScript() (which gives the option of redirecting the output to a log file) to return a status, so that it can be used in a CPF merge.

## Describe the solution

- A global flag (like -verbose) with a place to export the current device write outputs to.
- Additionally, it would be good to have a persistent modifier amongst the universal settings of a default location to write log files to (we can default this to somewhere under the DataDirectory()/ipm?).
- Also consider adding output of commands to the history table so we can see the log tied to specific command runs.
- Implementation wise, this should be able to **tee the output** to both a log file and the device terminal

## Additional context
Requested in internal reference TRIAGE-6911

Start by tracing how IPM shell commands write output to the current device and how ShellScript() exposes command status. Define the tee behavior, the default log location under DataDirectory()/ipm, and whether command output should be tied to the history table; completion requires decisions on these behaviors and their implementation.
