Add StMM wrapper SP
Add SP that acts as wrapper around StMM image. The StMM binary is
included as payload in the SP. Path to the binary must be passed in
STMM_BIN_PATH environment variable or CMake argument.
To start StMM the caller is responsible for two steps:
1. Share memory with this SP, which will act as the communication buffer
for StMM.
2. Send direct message to this SP to trigger initialization of StMM.
After StMM is launched, the control doesn't return to the wrapper SP.
The following files were derived from optee_os:
* gen_stmm_hex.py
* stmm-wrapper.h
