Add support for attachable/detachable minibuffer

* exwm-workspace.el (exwm-workspace--update-minibuffer-height): Renamed
from `exwm-workspace--update-minibuffer' to better reflect its usage.

* exwm-input.el (exwm-input--update-focus): Directly put the floating
X window at top since the minibuffer is no longer a sibling.
* exwm-workspace.el (exwm-workspace--resize-minibuffer-frame): Calculate
position in absolute coordinate; put minibuffer at bottom by default;
resize the minibuffer frame with ConfigureWindow rather than
`set-frame-width'.
(exwm-workspace-switch): No need to reparent minibuffer any more.
(exwm-workspace--on-ConfigureNotify): Calculate position in absolute
coordinate.
(exwm-workspace--show-minibuffer, exwm-workspace--hide-minibuffer):
Show/Hide the minibuffer by adjusting the stacking order rather than
mapping/unmapping.
(exwm-workspace--init): Map the minibuffer frame container on creation.

* exwm-workspace.el (exwm-workspace--minibuffer-attached-p):
New function telling whether the minibuffer is attached.
(exwm-workspace--attached-minibuffer-height): New variable storing the
height of the attached minibuffer.
(exwm-workspace-attach-minibuffer, exwm-workspace-detach-minibuffer):
New functions for attaching/detaching the minibuffer.

* exwm-workspace.el (exwm-workspace--show-minibuffer): Remove the
workaround for minibuffer cursor (seems fixed).
