Add ARM64 Linux layout support to score_log_bridge

[Subramanian-K812]

Summary

Adds arm64-linux platform support to score/mw/log/rust/score_log_bridge/BUILD
so that the C++/Rust log bridge builds correctly on aarch64-linux targets
(e.g. eb-aarch64 / ebclfsa SDK).

Why

The adapter cc_library and score_log_bridge rust_library both use a select()
to emit the correct layout-compatibility define (x86_64_linux, arm64_qnx, etc.).
Without an arm64-linux entry, builds targeting aarch64-linux fall through to
//conditions:default: [], meaning no define is set. This causes a compilation
failure in the C++/Rust FFI interface because the struct layout is undefined.

Change

• Adds a new config_setting(name = "arm64-linux", ...) for arm64 + linux.
• Adds ":arm64-linux": ["arm64_linux"] to the defines select in cc_library
  and the crate_features select in both rust_library and rust_test.
