Update EBcLfSA Integration to New Structure, add Rust support

[opajonk]

Update the EB corbos Linux for Safety Applications integration to the new structure of the repository.

• Uses https://github.com/eclipse-score/bazel_cpp_toolchains instead of previous score_toolchains_gcc
• Rust support for EB corbos Linux for Safety Applications is added
• Integration with //showcases:showcases done, build works, ./score_starter can be used
• Fixed fastdev sysroot for sandboxed builds

Missing: integration with "high-integrity-application-marking"; this needs to be done in a next step.

[opajonk]

Depends on:

• Add EBcLfSA Toolchain bazel_cpp_toolchains#28
• Enable aarch64 score-crates#25
• Add support for aarch64 ACL lifecycle#125

Looks fine for me , i will test this and then approve. Still I think we shall remove qemu from build phase and use loopdevice.

Tested locally, have few issues:

This will certainly require investigation. Apparently, the libacl introduced in baselibs has issues with static linking. However, this is nothing new and not due to the refactoring.

Also depends on use having some binaries like sshpass and then fails cryptically. Either bazelify or in script do checks for required tools to prompt user to install them

Added a check!

I was also able to get rid of the warning
