WIP: Upgrade to QuickJS NG

[richarddavison]

Description of changes

This PR upgrades LLRT to use QuickJS NG.

QuickJS-NG (Next Generation) is a better maintained community owned fork of the original QuickJS source. This fork has a lot of bug fixes, significant performance improvements and more recent ECMA support

1. Currently there are a few things that's broken. "performance" intrinsic is enabled by default and not writable. A PR has been merged in upstream making it writable
2. Custom allocators are causing segfaults
3. Also child_process rust tests are failing due to TypeId not being stable resulting in corrupted Class/Function Vtables. Very strange since it only behaves so for child_process rust test and not anywhere else.

Checklist

• Created unit tests in tests/unit and/or in Rust for my feature if needed
• Ran make fix to format JS and apply Clippy auto fixes
• Made sure my code didn't add any additional warnings: make check
• Added relevant type info in types/ directory
• Updated documentation if needed (API.md/README.md/Other)
