[0/9] devtool: ide-sdk clang/LLDB support and minor fixes

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

This series adds clang/LLDB support to devtool ide-sdk and contains
some bug fixes accumulated before the release.

Bug fixes and small improvements:

- Various selftest robustness fixes: use stat(1) instead of ls for
  user/group name lookups, switch to assertRegex, fix conf-file
  ownership with static UIDs/GIDs, add a GDB test that sets a
  breakpoint after std::vector construction.
- ide-sdk: use TOOLCHAIN instead of TCOVERRIDE to detect the active
  toolchain.
- ide-sdk debugger back-end: fix a typo (is_c_ccp -> is_c_cpp) and
  cleanly separate the debugger configuration from the IDE-specific
  launch/task file generation to simplify adding further back-ends.

Clang and LLDB support:

- ide-sdk: add LLDB (CodeLLDB) remote debugging support for the clang
  toolchain, including lldb-server target configuration, RecipeLldbNative
  host wrapper, source-map handling and VSCode launch.json generation.
- meta-selftest: refactor cmake-example and meson-example into shared
  .inc files and add clang variants (cmake-example-clang,
  meson-example-clang) to exercise the new toolchain path.
- oe-selftest: add end-to-end tests for devtool ide-sdk with the clang
  toolchain, including a full remote debugging session where the binary
  is compiled with clang and debugged with LLDB.
