Augment Razor view compilation exceptions to display errors

Improve the experience of Razor view template exceptions by including
the error messages in the output. When running outside of a debugger,
this information is otherwise nearly impossible to retrieve.

Prepended base path to routes on metadata page

The routes shown on the metadata pages assumed the API was being hosted
at the site root. If it was hosted in a subdirectory such as /api, the
subdirectory was omitted from the URIs, requiring the API user to
remember how to correctly form the URI.

Switched to 3.9.43.0 AssemblyVersion (consistent with other libraries)

All other assemblies in ServiceStack are built with an AssemblyVersion
matching the overall "product" version, currently 3.9.43.
Switched to GlobalAssemblyInfo approach for AssemblyVersion.

All projects in the ServiceStack.sln solution now pull their
AssemblyVersion attribute value from a single GlobalAssemblyInfo.cs file
at the src root, allowing this to be updated centrally. I did not adjust
the Android, SL, or WP projects.
