I agree with Martin that `tab-bar-height' should return a meaningful value
on --without-x builds too.

Please note this should be fixed on the release branch in Emacs 27.2
because the change in commit 6c5ddf0e0b was recently made in emacs-27.

I wonder why only tab-bar-height was added to frame-inner-height,
why not menu-bar-height as well?  Moreover, such function as
menu-bar-height doesn't exist at all.  Why only tab-bar-height is needed?
