Mk/bsd.options.desc.mk: add GTK4_DESC and minor improvements

- Provide shared GTK4_DESC and remove that from two ports
- Fix a typo (developement -> development), drop needless caps
- Spell AltiVec and BLAS (Basic Linear Algebra Subprograms)
  correctly (proper/brand name and abbreviation, respectively)
