bare-metal: Add IAR STM8 toolchain support

This commit adds a basic support of the IAR Embedded Workbench
toolchain for the STM8 processors family.

To use it with Qt Creator, it is enough to add there a desired Kit
with a custom IAR C/C++ compiler, and then set the following in the
Kit's Qbs profile settings:

* Key: qbs.toolchainType
* Value: iar

Tested with EW for STM8 v3.11.1 on Windows using the simple
projects samples which come with the default IAR installer.
