Support import with { type: "json" } and others

[pfgithub]

What does this PR do?

Fixes:

import config from "./.prettierrc" with { type: "json" };
console.log(config);
// before: /path/to/.prettierrc
// after: (contents)

await import("./some.file", {with: {type: "js"}});
// before: (crash)
// after: (imports some.file as js)

Breaking change: (bun.lock/tsconfig.json/... are unaffected) (must now use with {type: "jsonc"} or change the file path to .jsonc)

// a.ts
import config from "./my_jsonc_file.json"
console.log(config);
// before: `bun build a.ts` : works (different than `bun a.ts`)
// after: `bun build a.ts`: errors (same as `bun a.ts`)
