Enable bazel profiling in soong_build.

Bazel is executed several times during the execution of soong_build.
For each bazel execution, generate a profile and save under the
BAZEL_METRICS_DIR which is defined in soong_ui.

Bug: b/174479924
Test: * USE_BAZEL_ANALYSIS=1 USE_BAZEL=1 m nothing and checked
        if the cquery and graph build bazel profiles were generated.
      * Verified that the generated bazel profiles were uploaded
        to the local dev metrics pipeline.
