Disable __CxxFrameHandler4 when compiling HarfBuzz

[nulano]

Likely fix for #6701.

This is automatically enabled when compiling C++ with modern Visual Studio to reduce the binary size of try/catch blocks.
It uses VCRUNTIME140_1.dll, which is not available out-of-the-box, and needs to be included in the wheels.

However, I find there is almost no difference to the size of _imagingft.{...}.pyd when disabling it (disabling it actually saves 3KB), and it removes the need to include VCRUNTIME140_1.dll in the wheels.
