Behdad Esfahbod 9cd59db1af [USE] Implement topographical features for non-Arabic-joining scripts

Behdad Esfahbod 29832d797f Route misc untested scripts through USE shaper instead of Indic
These were never tested with Indic shaper, and indeed wouldn't work there
because they didn't have their viramas and other config defined.  They are
all also supported by MS through USE, so route them there.

Behdad Esfahbod 9ae156b768 Fix pragma usage
https://bugs.freedesktop.org/show_bug.cgi?id=91228

Commit cdcdfe61b9 changed two `#pragma
message` to `#pragma error` in hb-unicode.cc, however MSVC uses #error,
just like the #else branch. `#pragma error` is an unknown pragma so
MSVC does not fail the build because of it, which I believe was the
intention of that commit.

If it's meant to be an #error, then the #ifdef for _MSC_VER can be
removed entirely.
