docs: embed: add parameters to docstring
The docstring of IPython.terminal.embed.embed() does not document its
arguments. Add a "Parameters" section, and document each argument
appropriately:
- for 'header', rephrase the corresponding description from the
docstring of InteractiveShellEmbed.__call__, to which this argument is
passed (__call__ itself is missing from the generated API documentation
since sphinx.ext.autodoc does not document special members by default).
- for 'compile_flags', refer to the documentation of
InteractiveShellEmbed.mainloop, to which this argument is passed.
- for 'kwargs', refer to the constructor of InteractiveShellEmbed, and
fold in the sentence mentioning the 'config' argument.
