Function Compiler

Update function compiler to have multiple compilation stages, for better code generation

Adds support for macros in [tag] selector

Fixes bugs:

• Function runs with wrong ordering when calling a vanilla function from compiled function (affects 1.20.3+)
• Translatable text arguments with custom style don't generate style data
• execute if|unless function inside vanilla functions while calling compiled function runs too many times (affects 1.20.3+)
• Forking behaves as on bedrock instead of java
• Not all functions are found, some of the time
