compat/avisynth: update headers 

As part of the update, it is now possible to test 32-bit GCC builds
of AviSynth+ with FFmpeg by using the AVS_WIN32_GCC32 define. Due to
different calling conventions between MSVC and GCC regarding 32-bit
Windows, this is unfortunately necessary.

// NOTE: this is a partial update of the Avisynth C interface to recognize
// new color spaces added in Avisynth 2.60. By no means is this document
// completely Avisynth 2.60 compliant.
// 170103: added new CPU constants (FMA4, AVX512xx)
// 171102: define SIZETMOD. do not use yet, experimental. Offsets are size_t instead of int. Affects x64.
// 171106: avs_get_row_size calls into avs_get_row_size_p, instead of direct field access
// 171106: avs_get_height calls into avs_get_row_size_p, instead of direct field access
// 180524: AVSC_EXPORT to dllexport in capi.h for avisynth_c_plugin_init
// 180524: avs_is_same_colorspace VideoInfo parameters to const
// 181230: Readability: functions regrouped to mix less AVSC_API and AVSC_INLINE, put together Avisynth+ specific stuff
// 181230: use #ifndef AVSC_NO_DECLSPEC for AVSC_INLINE functions which are calling API functions
// 181230: comments on avs_load_library (helper for loading API entries dynamically into a struct using AVSC_NO_DECLSPEC define)
// 181230: define alias AVS_FRAME_ALIGN as FRAME_ALIGN
// 181230: remove unused form of avs_get_rowsize and avs_get_height (kept earlier for reference)
// 190104: avs_load_library: smart fallback mechanism for Avisynth+ specific functions:
// if they are not loadable, they will work in a classic Avisynth compatible mode
// Example#1: e.g. avs_is_444 will call the existing avs_is_yv24 instead
// Example#2: avs_bits_per_component will return 8 for all colorspaces (Classic Avisynth supports only 8 bits/pixel)
// Thus the Avisynth+ specific API functions are safely callable even when connected to classic Avisynth DLL
