securemsm: Add support for Bazel/Kleaf

Steps to test

1. Create symlink
    cd kernel_platform
    mkdir techpacks
    cd techpacks
    mkdir securemsm-kernel
    cd securemsm-kernel
    ln /vendor/qcom/open-source/securemsm-kernel/* .

2. To compile

    cd kernel_platfrom

    tools/bazel run  --lto=thin //techpacks/securemsm-kernel:pineapple_consolidate_securemsm-kernel_dist

3. Test done:

   Able to compile smcinvoke/tz_log/qseecom DLKM and able to install it
   at
   out/target/product/<target>/dlkm/lib/modules
