Introduce FEATURE_ keyword which behaves like TARGET_ but is generated from targets features (see targets.json)

Rename "features" to "device_has" in targets.json ...

"features" will make more sense in the context of the feature support
that we'll introduce later (related to #1878). Plus, "device_has" is
arguably a better description of the actual content of this key.

made features a first class citizen

added features support to all of the toolchains

RTOS - fix Cortex-M version - add macros required for new kernel ...

2 new macros were introduced to capture changes in the kernel. We used toolchains/__init__
script to capture those, which is not in the sync with actual sources. This fix introduces
those macros in the source, rather than a script.

We will further eliminate those macros to be used outside of RTX kernel (c++ API).

Removed colorama dependency. This breaks the online build system, the live exported and prevents deployment of new platforms. Rewrite the code so colors are optional and no additional modules are required for toolchains and platforms

trivial correction

Added IAR support for NRF51822. IAR's linker can not merge hex files as a section only binarys. I added a binary under TARGET_NORDIC/TARGET_MCU_NRF51822/TOOLCHAIN_IAR that represents the soft_device. I added support in the python scripts to also copy binaries to the build/mbed dir and also added support for the exporter to copy binaries from resources into the exported zip file.
