tdf#108580: integrate vc_redist.exe into MSI

... in InstallUISequense.

Use --with-vcredist-dir to point to a directory with vc_redist.x64.exe
and/or vc_redist.x86.exe. Use --without-vcredist-dir (or
--with-vcredist-dir=no) if you don't want to ship it as part of
installer and want to silence the configure warning.

VCRedist 2015 version 14.0.24215.1 is available at
https://www.microsoft.com/en-us/download/details.aspx?id=53840

Since VisualStudio 2015, VC redist merge module that we used before
started to work differently: it installs the UCRT only on WinXP,
but not on later OSes (Vista to 8.1) which may lack the UCRT (Win10
has it out of the box). The merge module only installs VCRuntime on
those systems, which still leaves us with "api-ms-*.dll is missing"
problem.

(https://blogs.msdn.microsoft.com/vcblog/2015/03/03/introducing-the-universal-crt/
gives more information on VCRedist refactoring background.)

Since commit 71d9a61302e65fe091cf70c13fa72b3df09b7e3a, we use a
workaround described at the page mentioned above as "App-local
deployment of the Universal CRT". We just copy all UCRT DLLs to
LibreOffice/program. This has a drawback though, that our UCRT
is not updated by Windows Update, so users would rely on LibreOffice
updates in case of some vulnerabilities in UCRT (and they could
even not realize they have that problem).

MS recommends to install UCRT using EXEs they provide from their
site. The EXEs install both VCRuntimes and UCRTs, along with
required patches, for all Windows versions (Windows XP through
Windows 10, where they only install VCRuntimes); the installed
libraries are managed by system's update mechanism. But those EXEs
cannot be used in MSI custom actions inside InstallExecuteSequence,
because they use MSI themselves.

So this patch integrates the vc_redist.xXX.exe into MSI binary
table, and uses custom action to run the EXE after ExecuteAction
in InstallUISequence. This will show the user a VCRedist install
window after the main LibreOffice installation finishes; no user
interaction is required (except for one additional UAC request),
and errors are ignored.

Since this installation takes care of both VCRuntime and UCRT,
we can ultimately drop both the app-local workaround, and
vcredist merge module (so VCRuntime would also be updated by
system). The former is done here: this reverts commit
71d9a61302e65fe091cf70c13fa72b3df09b7e3a.

This approach has its drawback: if one wants to use unattended
installation (without UI; one example is deployment using
ActiveDirectory GPO), then InstallUISequence is not run, and so
VCRedist isn't installed. In this case, one should install
VCRedist separately. Supposedly this should not be huge problem,
because this is the case for many existing applications that need
separate VCRedist deployment in these scenarios, and unattended
installation is advanced stuff that requires prepared user. A
notice would be required in release notes and FAQ, though.
