android: Allow zooming for Calc as well

The comment mentioning "Calc has a fixed zoom at 1x
and doesn't allow zooming for now" was there since
support for the Calc UI was added in commit
02f3c4848ab52358bfee56c570a19a3a071574f2  ("Calc UI
on Android Viewer") in 2017. That seems no longer to be
the case however, probably since commit
498dceb43f870bf9e380f1f87e99c6ccadf1963c
("sc lok: Implement hi-dpi and zoom for spreadsheets.").

Zooming in and out was working just fine when I tested this
with Android Viewer using a spreadsheet containing some text
and numbers, as well as a chart and an image.

Therefore, allow zooming for Calc as well.

Don't allow to set min zoom below the page width for Calc as
somewhat suggested by the existing comment ("applies to all
types of document; in the future spreadsheets may be
singled out"). I don't see a particular reason for this and
using 0f for minZoom would break double-tap zoom.
