sdm: Implement composer hidl directly.
- Implement the hidl .hal interfaces directly instead of
using the default shims.
- This is required since new additions to .hal will no
longer be added to the legacy hwcomposer C header.
- Create new composer process in INIT_RC
- Implement CommandQueue Reader and Writer
-Reader is used to parse the commands from
i/p CMQ of client
-Writer is used to write the outputs if any,
for parsed commands then o/p CMQ passed to client.
- Add IMapper support to clone buffer handles for HWComposer
-In IComposer, any buffer_handle_t is owned by the caller
and we need to make a clone for HWComposer.
- Implement composer 2.1 and 2.2 API's as well.
