overlookmotel 97caae16e2 refactor(minifier): do not use AstBuilder::*_from_* methods (#7072) 
Preparation for #7073. Avoid using `AstBuilder::*_from_*` methods to construct enums, use explicit construction instead.

Before:

```rs
let ident = self.ast.binding_pattern_kind_from_binding_identifier(ident);
```

After:

```rs
let ident = BindingPatternKind::BindingIdentifier(ident);
```

Often this produces shorter code, as well as (in my opinion) being easier to read.

Minifier

A JavaScript minifier has three components:

  1. printer
  2. mangler
  3. compressor

Mangler

The mangler implementation is part of the SymbolTable residing in oxc_semantic. It is responsible for shortening variables. Its algorithm should be gzip friendly.

The printer is also responsible for printing out the shortened variable names.

Compressor

The compressor is responsible for rewriting statements and expressions for minimal text output. Terser is a good place to start for learning the fundamentals.

Terser Tests
