feat: inline const for leaf modules

[ahabhgk]

Summary

Pre-PR for enum inlining

ref: evanw/esbuild@7bf3046

This PR only handle the cross-module part of const inlining, the idea is very similar to mangle exports:

1. Add inlinable on export_info, which is similar to can_mangle, and add UsedName::Inlined for inlined value and UsedName::Normal for maybe mangled names
2. Add inline_const parser plugin to find all the inlinable const variable, and "tag" it to tell the ESMExportSpecifierDependency that this exported value is inlinable

Inline const for the module that declared the const (in-module inlining) is not implemented yet, which need further discussion to decide:

1. Leave it all to minimizer, keep the behavior simple
2. Inline const for other top-level const declaration, which can help to find more inlinable const values, but may make the behavior more complex

Checklist

• Tests updated (or not required).
• Documentation updated (or not required update in future PR).
