feature request: Support outputting absolute paths in error messages

[domdomegg]

esbuild has a format messages API: https://esbuild.github.io/api/#format-messages

It would be useful if a property was added to FormatMessagesOptions, like pathType: "absolute" | "relative" which allowed users to control the output format.

This particularly helps for two cases:

• Monorepo setups, where relative paths might not be unique. Here, it allows distinguishing paths and so users can directly click links to the files with errors.
• Automated log reading tools, like GitHub's pattern matchers, to show errors in CI more easily.

Similar discussion for TypeScript is here: microsoft/TypeScript#36221

This would be incredibly useful.
