Backport v1 syntax changes

[markwpearce]

Allows:

• typed array syntax
• union type syntax
• using built-in component/object/interface/event types
• type cast syntax

This does NO additional validation. Use this syntax at your own risk.

In transpiled code:

• Typed Arrays are converted to dynamic
• Union types are converted to dynamic
• Built in types are converted to object (just like Classes/interfaces)
• Type casts are completely ignored and removed

Here are some examples:

Hey there! I just built a new temporary npm package based on fe568ee. You can download it here or install it by running the following command:

npm install https://github.com/rokucommunity/brighterscript/releases/download/v0.0.0-packages/brighterscript-0.65.18-backport-v1-syntax-changes.20240129152809.tgz

@markwpearce I just tested this out in our project, and I'm seeing a few small issues:

1. return types have errors for the built-in types
   
2. names in extends sections have errors for known types.

Everything looks great! I tested on our internal project and have no issues.
