feat(tvix/eval): fancy-format parse errors returned by rnix r/5063
This change is quite verbose, so a little bit of explaining: 1. To correctly format parse errors, errors must be able to return more than one annotated span (the parser returns a list of errors for each span). To accomplish this, the structure of how the `Diagnostic` struct which formats an error is constructed has changed to delegate the creation of the `SpanLabel` vector to the kind of error. 2. The rnix structures don't have human-readable output formats by default, so some verbose methods for formatting them in human-readable ways have been added in the errors module. We might want to move these out into a submodule. 3. In many cases, the errors returned by rnix are a bit strange - so while we format them with all information that is easily available they may look weird or not necessarily help users. Consider this CL only a first step in the right direction.
