[PATCH 6/9] oe-selftest: devtool ide-sdk: test install task

[AdrianF <adrian.freihofer@siemens.com>]

From: Adrian Freihofer <adrian.freihofer@siemens.com>

Verify that the ide-sdk setup generates the do_install task script and that
the script runs successfully. This covers the prepared-task runner used by
the IDE deployment workflow without requiring Qemu.

Replace the ad-hoc dependsOn handling in _verify_launch_config() with a
new helper that mirrors VS Code's task dependency resolution and
execution order. This ensures that the selftest runs the same sequence
of tasks as VS Code would, including compile and install/deploy
prerequisites, before starting the debug server. This also aligns the
gdb and lldb selftest paths to avoid behavior drift and improve test
reliability.
