feat(eval): add oxc_eval crate

[DonIsaac]

Closes #6473

What This PR Does

Adds oxc_eval, a new crate for evaluating parsed JS code. It contains the following:

1. Data types implementing various parts of the ECMAScript spec
2. Evaluation runtime semantics for most AST nodes.

Goals

1. consolidate constant eval semantics used throughout oxc crates (e.g. const folding in the minifier, const eval in oxc_isolated_declarations, etc)
2. Provide spec-compliant implementations of data types (e.g. CompletionRecord, Number, etc) to consuming applications
3. Support future tree-shaking endeavours

Scope

The following are not in scope:

1. A full JavaScript interpreter (e.g. a full implementation of the ECMAScript spec)
2. Non-trivial runtime semantics (e.g. full EnvironmentRecord and import/export semantics)
3. Garbage collection
4. Any form of bytecode or bytecode interpreter
