Modify the build method of TizenRT target

Introduced a cmake/toolchain_mcu_artik053.cmake file that defines
all the target specific compiler options.

Modified the Makefile.tizenrt to do not copy the created static
libraries to the TizenRT folder. Instead, the application builder
Makefile (tizenrt-artik053/apps/jerryscript/Makefile) copies the
required static libraries to TizenRT.
