tdf#108580 related: improve existing redist detection

This uses VC Runtime upgrade code (checked using Upgrade table) to
find installed redist, instead of checking registry keys that change
between versions (while the runtime is still compatible, as with 2015
and 2017).
Also, it checks if UCRT is present. Now, if either VC Runtime or UCRT
is absent, we try to install the redist. This would allow to install
UCRT in scenarios when first install was attempted on a system not
suitable for UCRT (like Win7 w/o SP1, or Win8.1 w/o April 2014 update
rollup), where VC Runtime gets installed, but UCRT is still missing.
We use the ucrtbase.dll version to check that; and as the expected
version is 10.x, we take into account that Win10 lies about versions.
