android: fix some layout issues with new-document buttons

functionality to create new documents was added for tdf#106325 with
commit 1503769fe15c122ff2bb8f6f7e7b4ab72656ddc2
However the commit had some issues, most notably clipping of the shadow
effect and alignment issues to to scaling down (via the animation
effect, took me quite a while until I looked at that) with having a
centered pivot. I think it was due to those alignment issues that the
label was set to a fixed with - which is a problem for future
translation.
This commit:
* changes the animation to not scale down the initial views
* changes the FABs' setting to use compatPadding - this not only ensures
enough room for the shadow, but also allows for consistent look across
android versions. Side effect is that it needs more height, so
* the effect was adjusted accordingly, to shrink to/expand from the
lower-right corner of the parent view, instead of "mid-air"
* the labels were given a proper background drawable with rounded
corners and some padding for a (much more9 polished look
* formatting of the labels was split out to a style, for ease of
tweaking the looks
* add tools:visibility statement to see the elements in layout editor
* fixed the strings for the labels (and ID) to some less awkward ones
