Visual Studio builds: Add optional rules to generate translations

Add a target in the install-msvc.mak file that enables one to generate
the translations (.mo) files using msgfmt from the .po catalog files.

Add an entry in config-msvc.mak[.in] so that one can use it to configure
a custom location for the msgfmt.exe program, since it is harder to
install with Visual Studio, so that one can use a prebuilt copy from
Cygwin or MSYS2, for instance.

+=========================\r
+Building translations is supported via Meson builds or via the Visual Studio projects,\r
+both of which require a working msgfmt.exe (from gettext-tools, a part of gettext) in the\r
+PATH, or for the Visual Studio projects, passed into the arguments in "InstallBuildsBase"\r
+in gtk3-build-defines.[props|vsprops] with MSGFMT=xxx.  For the Visual Studio projects, for\r
+this to work one needs to also supply a "INSTALL_TRANSLATIONS=1" (without the quotes)\r
+argument to the same "InstallBuildsBase" in the afore-mentioned property sheet.  Using\r
+msgfmt.exe from Cygwin or MSYS2 is supported as well.\r
