Re-Add Static File support

[SentryMan]

Adds support for creating handlers that serve static resources.

• Adds a StaticContentConfig class that will construct a handler to serve files
• Adds three static handlers. one for regular files, jars and another for more esoteric cases like when using jlink
• Re-add some Basic HttpResponse Exceptions (we don't need as many as we had before, but catching framework errors is pretty useful)

[SentryMan]

hmm, it would seem that it doesn't properly load when running a modular jar outside of jlink

@rbygrave please review when you find time

I think we should be good for an RC so I can try this stuff out for real. Unless you have some other ideas for features?

good for an RC

Yeah cool. I'll roll one out when I get home.

I will look to add a separate helper module to avaje-jex to support htmx features (to match the htmx support we have for nima/helidon).
