Add support for updating the *Completions* buffer as you type,
controlled by a new completion metadata symbol 'eager-update and
new defcustom completion-eager-update.

You can configure a completion category to update *Completions*
as you type by setting completion-category-overrides
appropriately; or set completion-eager-update to t to always
update *Completions* as you type.

This is similar to the recently added completion-eager-display.
