Evgeniy Paltsev 497cb2e587 CPP: fix static objects init for MWDT toolchain 
The constructors of static objects are stored in ".ctors"
section. In case of MWDT toolchain we have incompatible
".ctors" section format with GNU toolchain. So let's use
initialization code provided by MWDT instead of Zephyr one
in case of MWDT toolchain usage.

As it is done for GNU toolchain We call constructors of
static objects but we don't call destructors for them.
