Target + Exporters - progen data expansion by template for tools ...

Each target can specify own template. This is however not recommended for general use.
Each target should be supported by progendef, and well definied. However, as tools are
quickly changing, some targets add extra information which might not be supported, this
template expansion allows a target to temporary override default mbed tool template.

In this commit, we add RZ_A1H iar template. I experienced with never tools some breakage in
the templates, this might come handy, but repeat, please consider using the default template, and
contribute to progen or progendef which should contain fixes or support for newer targets/tools.

Exporter IAR - fix issupported argument - string

Exporters IAR - use template from older mbed templates

Exporters IAR - fix template path

Exporters IAR - add template mbed file

Exporters iar - add comments to IAR progen implementation

IAR - add TARGETS for backward compatibility

Export - IAR progen addition ...

The IAR exporter is replaced by progen.

Support of export function to the IAR. ...

We modified the following to support the export function to the IAR.
- In tools files, add RZ_A1H to the target of IAR.
- In tools files, add the tmpl files.

Add EFM32 Pearl Gecko exporters.

Add exporters for the new platform + add it to build and tests files
