elementary_test: italic and bold

[joaoantoniocardoso]

In elementary_test, any textbox or label should be able to display bold and italic text.

Expected behavior

• Text inside <b>bold</b> markup tags should be displayed in bold
• Text inside <i>italic</i> markup tags should be displayed in italic

Actual behavior

• The text inside bold or italic markup tags is being displayed as normal text.

Steps to reproduce

In elementary_test:

• Entry Style Default should display some text in bold and some in italic
• Efl.CanvasTextblock style should display bold if the style string font_weight=bold is added in the text box.
• Efl.CanvasTextblock style should display italic if the style string font_style=italic is added in the text box.

Since the merge of PR #441, this is no longer an issue if using fontconfig. To do so:

1. install it with vcpkg by running vcpkg install fontconfig:x64-windows
2. then it needs to be enabled in the configure.bat by settting -Dfontconfig=true
3. also, the ambient variable fontconfig_file must be set to the location of the file fonts.conf of your fontconfig instalation, eg: C:\src\vcpkg\installed\x64-windows\tools\fontconfig\fonts\fonts.conf.
