[glyf] Optimize retrieval of hmtx/vmtx/gvar 
This should make glyf/gvar faster as makes it to invoke less table wrapper atomic operations and things.

[meson] Pass cpp_eh=none and cpp_rtti=false as default options 
If we want to support a build with exception handling and RTTI
We should reflect that on library(..., link_language: 'c') also so for
now it is ok to just set it here to get MSVC support also and we
can remove hard coded flags later upon request.

One other concern over just relying on it is on when harfbuzz is used
as a subproject and the parent project hasn't provided the same options,
that should be resolved first I think.

Closes #2584

[meson] remove useless note about -fvisibility-inlines-hidden 
It was put there as current situation of autotools but msys2 is ok
with the flag, if something like is needed for other it can handled
as a local patch.

[meson] limit check-libstdc++ check to 0.55 
library(..., link_language: 'c') is introduced in 0.55 but we were relying on this anyway
assuming b_asneeded being true on meson.

9d3fbe0588 [meson] Add darwin versions to library()

$ otool -L src/libharfbuzz.dylib
src/libharfbuzz.dylib:

And with the change should we get

$ otool -L src/libharfbuzz.dylib
src/libharfbuzz.dylib:
	@rpath/libharfbuzz.0.dylib (compatibility version 20700.0.0, current version 20700.0.0)
