Zhao Zhili 9ebfd68096 swscale/swscale: force SwsDither and SwsAlphaBlend to 32 bits 
The 'sws_dither' and 'alphablend' options access 'SwsDither' and
'SwsAlphaBlend' enum fields as integers. This is unsafe when the
code is compiled with -fshort-enums, as the enum size might be
smaller than an int.

Since the 'dither' and 'alpha_blend' struct members are part of the
public API, their types cannot be easily changed.

To ensure safe integer access and maintain ABI compatibility across
different compiler settings, a MAX_ENUM value is added to force the
enums to a 32-bit underlying type.
