cerbero: Fix loading of rsvg, ttmlsubs, resindvd under MSVC

We were setting `objc` as `[]` in the native file, because of which
meson was auto-detecting it and finding it inside the MSYS-MinGW env.
Then it was using that (instead of the MSVC compiler) to search for
libraries inside `dependency()` and picked the GCC-compatible import
libraries (`.dll.a`) for all dependencies, such as cairo, pango,
libxml2, fontconfig, etc.

The MSVC linker tried its best to chug along and mostly succeeded, but
possibly due to format incompatibilities between `.dll.a` and `.lib`
import library formats or bugs in GCC and/or MSVC, this led to the
linker getting confused and looking for some libxml2 symbols both
inside cairo *and* libxml2 DLLs, and doing the same for some cairo
symbols too.

For example, it was looking for `xmlDocGetRootElement` and
`cairo_create` in both `libxml2-2.dll` and *also* in `libcairo-2.dll`.

Since in PE images multiple references to the same symbol in different
DLLs is allowed and all these references must be resolved at runtime,
this was a runtime error not a build-time error. The same thing was
also happening to resindvd.

Oh, also re-enable resindvd which was accidentally disabled on MSVC
when it was supposed to be disabled on UWP.

Closes #277
