    doc/filters: fix typo in format filter

The inline example for option color_ranges used 'color_spaces'

    avfilter/scale*: add option reset_sar

For anamorphic videos, enabling this option leads to adjustment of
output dimensions to obtain square pixels when the user requests
proportional scaling through either of the w/h expressions or
force_original_aspect_ratio.

Output SAR is always reset to 1.

Option added to scale, scale_cuda, scale_npp & scale_vaapi.

libplacebo already has a similar option with different semantics,
scale_vt and scale_vulkan don't implement force_oar, so for these
three filters, I've made minimal changes needed to not break building
or change output.
