cryptfshw: Introduce QSEECom backend implementationlineage-17.0

Some code snippets are taken from the following set of changes:

    cryptfshw: Setup boilerplate items before actual implementation

    * This is also in preparation for splitting this into two impls:
      one for ioctl() calls and one for dlsym() calls
   * This includes:
    - Add a .clang-format file and format the source
    - Add an init rc file
    - Add service.cpp
    - Convert struct to a class
    - Setup Android.bp for building the HIDL hal and run through bpfix
    - Setup items shared between both impls in Android.bp
