[00/19] devtool: ide-sdk: Enhance debugging and testing

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

This patch series enhances the devtool ide-sdk functionality with
improvements to debugging capabilities, service integration, and
developer workflow optimization.

Enhancements:
- GDB Pretty-Printing: Added support for C++ STL type pretty-printing
  using GCC Python helper scripts, making complex STL containers
  readable during debugging sessions
- Multiple Debug Modes: Introduced gdbserver attach mode support for
  debugging running services alongside the existing --once mode
  - Service Detection: Automatic detection of binaries that run as
    services.
    For these binaries an additional --attach debug configuration gets
    generated.
- Improved Path Mapping: Enhanced DEBUG_PREFIX_MAP evaluation for
  better source file location during remote debugging
- BitBake-Free Deployment: Eliminated bitbake dependency during daily
  development workflow, making deployment self-contained and faster.
  This patch was rejected one or two years ago. Usually I try to not
  "send the same crap again". However, I think the situation changed a
  bit, since then:
  - All alternative approaches which were discussed turned out as not
    feasible. bitbake -b does not work.
    Bitbake's server mode does no longer observe the recipes via
    inotify. This gives up the idea of using bitbake as a server
    running behind an IDE.
  - The patch proved to work very well and did not break since more
    than a year or two? So it does not seem to be that problematic.
    If that would change, reverting it should be possible at any time.
  - Using the ide-sdk with this patch versus without this patch makes a
    major difference from a usability perspective. It's much quicker
    and it's much more predictable.
- Kernel Module Support: Basic support for kernel module development
  with proper environment setup. There is no automated deployment or
  e.g. support for kgdb. But compiling works as for other plugins.
- VSCode plugin: Write the commands for starting the remote gdbserver
  directly into the launch.json file which makes it much simpler to
  understand and tweak.

Testing improvements:
- Systemd/SysV Support: Extended C++ examples to run as both one-shot
  executables and long-running services with proper user/group
  management for two reasons:
  - Testing remote debugging with attached mode
  - Test the deploy script which runs on pseudo and should preserve the
    user and group flags also during the development.
- Added full remote debugging test coverage for VSCode with launch.json
  and tasks.json with Qemu.
- GDB pretty-printing validation for STL containers
- Proper file ownership verification with pseudo
- Added comprehensive debug logging and better error reporting for
  oe-selftest -r devtool.DevtoolIdeSdkTests
