On Windows, module resolver does not handle junctions or symlinks correctly

[Jarred-Sumner]

On Windows, Bun's module resolver does not detect correctly that a junction is a directory. We think it is a file. We try to read it from a file. And the code for reading files doesn't expect to receive a directory, causing it to return Unexpected.

Related issues:

• bun run --bun does not work with pnpm (works with npm and bun install) [windows exclusive?] #10013
• Problems with Windows directory junctions #10172
• Some monorepos do not work on Windows #10125

Can we please prioritize this? Monorepos basically just don't work at all on Windows.
