Absolute Windows paths are handled as invalid URL path in ESM import()

Version: v14.8v0
Platform: Windows
Subsystem:

Related: #31710

What steps will reproduce the bug?

Windows paths are interpreted as invalid file URL. In Linux and Mac, the issue can't be reproduced.

Fail

await import("D:\repositories\fastify-autoload\routes\hello.mjs")

Works

await import(url.pathToFileURL("D:\repositories\fastify-autoload\routes\hello.mjs").href)

Root cause

#31710 (comment)

What is the expected behavior?

Interpret windows paths as valid URL paths so we can provide consistent cross-platform behaviour.

What do you see instead?
