bfredl cf07f2baab feat(edit)!: remove old c implementation of hebrew keymap
This feature has long been obsolete. The 'keymap' option can be used
to support language keymaps, including hebrew and hebrewp (phonetic
mapping). There is no need to keep the old c code with hardcoded
keymaps for some languages.

// User-settable options. Checklist for adding a new option:
// - Put it in options.lua
// - For a global option: Add a variable for it in option_defs.h.
// - For a buffer or window local option:
// - Add a BV_XX or WV_XX entry to option_defs.h
// - Add a variable to the window or buffer struct in buffer_defs.h.
// - For a window option, add some code to copy_winopt().
// - For a window string option, add code to check_winopt()
// and clear_winopt(). If setting the option needs parsing,
// add some code to didset_window_options().
// - For a buffer option, add some code to buf_copy_options().
// - For a buffer string option, add code to check_buf_options().
// - If it's a numeric option, add any necessary bounds checks to
// set_num_option().
// - If it's a list of flags, add some code in do_set(), search for WW_ALL.
// - Add documentation! doc/options.txt, and any other related places.
// - Add an entry in runtime/optwin.vim.
