Add libxml2, sqlite, and tree-sitter for the Emacs feature set

Message

These are the leaf dependencies behind Emacs' shr/eww rendering, its built-in sqlite- functions, and the -ts-mode major modes. None has a package dependency, so all three land in one publish level.

tree-sitter is the first definition here that does not fit the configure/make/install shape: it ships no configure script, only a Makefile driven by PREFIX and DESTDIR. Omitting the configure phase and passing PREFIX=/out to the other two works, but only because that Makefile happens to accept the variables the phase model already sets. The module header records that, since plain-Makefile is not exotic.

jansson is deliberately absent. Emacs 30.2 does not use it: zero references in configure.ac or configure, no --with-json, and JSON is in-tree at src/json.c with DEFUN ("json-serialize", ...). Guix's dependency list for emacs-no-x carries it vestigially. Checked rather than inherited, with a positive control -- the same grep finds 15 to 33 references to each dependency Emacs really does have.

Executed all three: sqlite runs a real query and the JSON1 extension, xmllint resolves XPath over HTML and XML and rejects malformed input, and tree-sitter drives its parser API through both the static and the shared library.
