Add classic-diagnostic-adapter dependency with git override

[opajonk]

• Introduced a new bazel dependency for classic-diagnostic-adapter of OpenSOVD
• Added git override for classic-diagnostic-adapter to specify the commit and remote repository (tracks Draft: add basic bazel build (S-Core Integration) eclipse-opensovd/classic-diagnostic-adapter#348)
• First test is to build this, with the default toolchains

bazel build @classic-diagnostic-adapter//:opensovd-cda --experimental_isolated_extension_usages --@classic-diagnostic-adapter//:tls_backend=mbedtls

which passes for me right now like this:

Note especially the patches mentioned in bazel_common/score_modules_target_sw.MODULE.bazel. They are required to make the build pass; for cross-compilation, two more patches are needed (commented out). Those are horrible patches which contains hard-coded, architecture-specific paths and can be considered PoC at best.
