Add thermald adaptive engine startup test (New)

[snalvc]

Description

Add test for checking thermald's adaptive engine startup by monitoring its output.

Resolved issues

SOMERVILLE-2442

Documentation

This test launches thermald with adaptive engine and uses grep to detect which pattern appears first:

• SUCCESS: "Start main loop" - adaptive engine started correctly
• FAILURE: "Also unable to evaluate any conditions" - adaptive engine failed,
  thermald falls back to highest power profile

The test captures the first occurrence of either pattern to determine if the adaptive engine initialization was successful.
