app-doc/doxygen: add 1.9.8

* Drop unnecessary patch for bad encoding (upstream note it shouldn't be required
  anymore, see https://github.com/doxygen/doxygen/issues/10258#issuecomment-1693323707)

* Drop/alter libcxx patch. Use the upstream build option, although tweak it
  to always be "available" to avoid unused var warnings w/ cmake.eclass
  (see patch comments for details)

* Backport fix for spdlog building (although I didn't hit this issue myself)

* Backport sqlite unbundling

* Rename USE=qt5 -> USE=gui per QA policy

Closes: https://bugs.gentoo.org/912986
