Make code more compatible with typedoc

[TheLazySquid]

This PR is on top of #2134, and changes BD's code to be friendlier to typedoc for this docs PR. Changes include:

• Boundable apis have been split up into a bound and non-bound version so the signature is readable
• Things like ReactUtils and Webpack have been converted into classes so they get documented better
• Function arguments have all been given names
• All namespaces on BdApi instances are getters for consistency
• API classes now have @ignored constructors
  • The eslint rule "no-useless-constructor" has been disabled to accommodate this
• Parameter names have been changed to match jsdoc

Code Review

This pull request performs a major TypeScript migration and refactoring of the BetterDiscord API, introducing 'Bound' class variants for plugin-scoped instances and a new build process for bundled type declarations. The changes involve extensive type annotations across core modules, stores, and UI components. Feedback identifies a potential runtime error in the context menu builder due to a missing label check and critiques a risky pattern in the BdApi class where prototype getters return unbound instances despite being typed as bound ones.
