Update documentation for emacs and split for LSP and Eglot modes
Emacs has now two LSP clients, the more minimalistic and lightweight Eglot and
the extensive though a bit bloated LSP-Mode. Eglot will soon be
shipped with Emacs29. Both have rust-analyzer enabled by default and require
no further setup then just being installed and enabled. `lsp-rust.el` is not
required anymore.

The base-installation for each of those modes is so easy now that I don't think
an enumerated list is necessary, both package can be installed via the standard
`M-x package-install` and the installation is a one-liner that I provide.

Configuration mostly comes into play for support the rust-analyzer extensions to
the LSP protocol, which are built into LSP mode and require an extension-package
for Eglot.

But for the configuration beyond the base configuration I link against official
documentation, quickstart guides and documentation for the lsp extensions, to
avoid showing outdated information here.

This commit is mostly a duplicate of a PR [1] that I made against the
rust-analyzer github project.
