This change introduces new fields on `lv_disp_drv_t` that allow to
specify the size of the full display and the offset of the display
subsection that is being rendered to. The values are used to transform
the drawing area before calling `flush_cb` so that only the desired part
of the full display is being rendered to.

This commit replaces the current `actual & expected` check in
`lv_btnmatrix_has_btn_ctrl` with `(actual & expected) == expected`. This
is required to make the function work with ORed control flags because
otherwise a parity in *any* bit will result in a return value of `true`
even if not all expected bits are set.
It was used to position the text in one line text areas where the label is shorter then the text area itself.
However, setting min_width=100% in case of one line text area ensures that the label is at least as wide as
the text area. This way the normal text_align style property can be used too.

Prior to this commit, when the title string was empty and the close
button disabled, an extra empty line showed at the top of the message
box. This commit prevents adding the title label unless it has content
or is needed as a spacer for the close button.
As a positive side effect, this also prevents the default "text" from
displaying when NULL is passed as the title.

This adds a new function lv_msgbox_get_active_btn that works analogously
to lv_msgbox_get_active_btn_text but returns the button index instead of
its text.
The index is more convenient for comparison in localized applications as
it doesn't depend on the current language.
