use clang-cl's -Zc:dllexportInlines- for Skia (tdf#144598)

This is clang-cl's equivalent of -fvisibility-inlines-hidden,
and it seems to be also sort of the equivalent of MSVC's
-Zc:inline. So it saves build time and disk space.

As an additional effect, this disables emitting copies
of inlines functions in every .o file where the function
is called (even if inlined), which means that it hopefully
avoids the problem of SkOpts_avx.cpp generating a copy
of SkRect::round() which would include AVX code, and
the linker might select this as the instance of SkRect::round()
to keep, thus making SSE2 code call AVX code without checking
for AVX availability first.
