BareMetal: Add STM8 architecture for SDCC toolchain

Browse Source 
Previous implementation of SDCC toolchain based on an assumption,
that the default target architecture always is MCS51.

But, the SDCC compiler support multiple architectures:

* http://sdcc.sourceforge.net/

Since we have the new STM8 architecture in the Abi::Architecture
enumeration, it is makes sense to add support for this architecture
and to the SDCC compiler.

Right now, the SDCC compiler will be auto-detected as two instances:

* with mcs51 architecture
* with stm8 architecture

by analogy as it does for the MSVC compiler for multiple x86, x86_64
and so forth architectures.

In case the SDCC compiler is manually added, the user can choose
a desired architecture (mcs51 or stm8) from the combo-box.
