LT-22230: Add a method to increase the font size of parser test reports

[jtmaxwell3]

This fixes https://jira.sil.org/browse/LT-22230. Whenever styles are edited then RefreshPopupWindowFonts is published. ParserListener subscribes to RefreshPopupWindowFonts and calls SetFont on each of the parser report windows to update the font. I changed the XAML files so that they would work with different font sizes. I also had to make ShowParserReport use the Pub/Sub model because it couldn't be a static function anymore because I needed m_parserReportDialogs to keep track of the parser reports.

Src/LexText/ParserUI/ParserListener.cs line 847 at r1 (raw file):

				ReadParserReports();
				// Create parser reports window.
				m_parserReportsDialog = new ParserReportsDialog(m_parserReports, m_mediator, m_cache, m_propertyTable, m_defaultComment);

Instead of using Pub/Sub to get to the ParserListener.ShowParserReport() can you add a ParserListener parameter to the ParserReportDialog constructor and the ParserReportsDialog constructor. They both look like they are only called from ParseListener so I think you can pass in 'this'.
