[GnoVM] Make error line clickable

[leohhhn]

Description

Would be cool and good for UX to make the error line clickable so it takes you to the location of the error, such as here:

❯ gno test . -v 
.: test pkg: panic: gno.land/r/gov/dao/v2/render.gno:45:12: name ResolveAddress not declared:
--- preprocess stack ---

Do you think this is feasible/practical?

I'm not sure how editors make it work honestly; but I think it needs to be either 1. at the beginning of a newline or 2. an actual relative file, rather than being a package path. Would be good to find some references to how to actually make this "clickable" in mainstream editors.

Usually, using the format filename:line_number:column_number allows the IDE to process logs through parsing internally.

Or, we can also use OSC 8¹ hyperlink escape sequences enables more explicit handling. This method can also be work over a external terminal, such as iTerm.

For example, it takes the following form (we can use other schemes also):

\033]8;;file://path\007text\033]8;;\007

However, I believe that in most cases, simply applying the first method with a consistent format should be sufficient without any issues.

To share a bit my progress, my idea on how to make this happen is to replace the String() representation of Location type to replace the package path (gno.lang/p/demo/ownable) by the actual location of the package inside the file system.

I started a draft to make it happen, however after more considerations. The issue that rise is that I need to store the filepath inside every nodes so the string will be duplicated too much.

So far, I am trying to find another cleaner way.
