Load *.{m,c}ts{x} last in node_modules

[Jarred-Sumner]

What does this PR do?

Bun currently loads .ts and .tsx files first. This usually works great in local development. This doesn't always work in node_modules because some projects will need special tsconfig.json options which we do not support to work:

• ts transformer plugins
• using import {Foo} rather than import {type Foo} or export {Foo} rather than export {type Foo}

This fixes that by only choosing .{m,c}ts{x} first when not in node_modules

I'm marking this as a draft because the logic currently only applies to the main/index file and it needs to also apply to the extension order. We can't merge this until that's fixed. Fixed

Fixes #5426
