Add Bun.Glob

[zackradisic]

What does this PR do?

Still WIP

This adds a Glob class to bun which implements glob pattern matching on filesystem/strings.

Basic example:

import { Glob } from "bun";

const glob = new Glob("**/*.ts");
const entries = await glob.match({ cwd: "src" });

console.log("Entries", entries);

This adds

• Documentation or TypeScript types (it's okay to leave the rest blank in this case)
• Code changes

Still need to do:

• symlink support
• more comprehensive tests (see blow)
• return async iterator for Glob.scan()

How did you verify your code works?

I wrote automated tests:

• Basic tests for glob matching/walking
• Copy tests from fast-glob
• Weird edge case tests (invalid surrogate pairs, filenames with latin1 characters, etc.)
• Stress tests

If Zig files changed:

• I checked the lifetime of memory allocated to verify it's (1) freed and (2) only freed when it should be
• I or my editor ran zig fmt on the changed files
• I included a test for the new code, or an existing test covers it

If new methods, getters, or setters were added to a publicly exposed class:

• I added TypeScript types for the new methods, getters, or setters

If dependencies in tests changed:

• I made sure that specific versions of dependencies are used instead of ranged or tagged versions

If *.classes.ts files were added or changed:

• I ran make codegen to regenerate the C++ and Zig code
