ComponentViewer: added basic string support for var usage

[thorstendb-ARM]

Changes

• <var> now supports usage as string array, value="text" sets the default.
• inside <calc> array manipulation is possible

      <var name="msg" type="uint8_t" size="128" value="&quot;Hello, World:&quot;"/>
...
        <item property="List count test">
          <list name="ListCountTest" start="0" limit="10">
          <calc>
            ListCount=ListCountTest+1;
            msg[ListCount &amp; 0x7F]='_';
          </calc>
          <item property="ListCountTest" value="%d[ListCountTest]"/>
          <item property="ListCount" value="%d[ListCount]"/>
          <item property="Name Test" value="%t[msg] %d[ListCount]"/>
          </list>
        </item>

@jreineckearm I've opened a new pull request, #916, to work on those changes. Once the pull request is ready, I'll request review from you.

Happy to merge once we at least have a ticket for the required spec updates here: https://github.com/ARM-software/CMSIS-View/issues and addressed the review feedback.

[jreineckearm]

Created ARM-software/CMSIS-View#160 to cover the known enhancements compared to existing spec.
