fix: polyfills for Node.js compatibility

[jcbsfilho]

This pull request introduces significant updates to the unenv-preset package, focusing on enhancing Node.js polyfills and improving the https request implementation. It also includes some minor code simplifications and reorganization. Below is a categorized summary of the most important changes:

Enhancements to Node.js Polyfills:

• Added a comprehensive set of utility functions and classes in internal/util to mimic Node.js behavior, including inherits, MIMEType, MIMEParams, promisify, and various type-checking utilities like isRegExp and isDate. These updates improve compatibility with Node.js APIs. [1] [2] [3] [4] [5]
• Introduced a new util.js file that consolidates exports from internal/util, providing a single entry point for utility functions and polyfills.

Improvements to https Request Implementation:

• Refactored the request function in https.js to support additional options (urlOrOptions and optionsOrCallback) and handle headers, methods, and body formatting more robustly.
• Added support for setting and removing headers dynamically via setHeader and removeHeader methods.
• Enhanced response handling by implementing an async iterator for streaming response data and improving chunk processing.
• Made the timeout duration configurable via the options.timeout parameter.

Code Simplifications and Minor Changes:

• Simplified the default export in polyfills/promises/index.js by directly exporting promisesContext.
• Added new polyfill paths for util and util/types in the unenv-preset configuration.

These changes collectively enhance the functionality and compatibility of the unenv-preset package, particularly for environments requiring Node.js polyfills.
