Description of Change

When the XamlParser throws an exception while executed from XamlC, the file info is missing from the log, and the whole XamlC process fails, so it only reports one issue at a time.

It now logs things like

/Users/sde/Projects/Microsoft/maui/src/Controls/tests/Xaml.UnitTests/Issues/Maui21038.xaml(8,10): XamlC error : 'Label.Text' is a duplicate property name. [/Users/sde/Projects/Microsoft/maui/src/Controls/tests/Xaml.UnitTests/Controls.Xaml.UnitTests.csproj]

Issues Fixed

Fixes #21038
