Reviewed by Anders Carlsson.

Source/WebCore:

Do not add "Check Grammar With Spelling" and "Ignore Grammar" to the context menu
when GRAMMAR_CHECKING is off.
Replace "Spelling and Grammar" with "Spelling" as the sub menu title and "Show/Hide Spelling
and Grammar" with "Show/Hide Spelling" when GRAMMAR_CHECKING is off.

Additionally, guard grammar checking in context menu code to not necessarily
compile it.

No new layout tests because every port has a different way of showing
spelling/grammar context menu items.
