Add -fsuppress-error-contexts to disable printing error contexts in errorswip/diagnostics-config
In many development environments, the source span is the primary means
of seeing what an error message relates to, and the In the expression:
and In an equation for: clauses are not particularly relevant. However,
they can grow to be quite long, which can make the message itself both
feel overwhelming and interact badly with limited-space areas.
It's simple to implement this flag so we might as well do it and give
the user control about how they see their messages.
Fixes #21722
