This brings ff_vf_ssim360 in line with its declaration in allfilters.c;
this discrepancy is actually undefined behaviour.

The FILTER_INPUTS and FILTER_OUTPUTS macros already set
AVFilter.(inputs|outputs); Clang therefore emits a warning for
this: "initializer overrides prior initialization of this subobject
[-Winitializer-overrides]"

Don't use "static const" for compile time float constants, but use
defines. This fixes the following error:

The same members between QSVVPPContext and VPPContext are removed from
VPPContext, and async_depth is moved from QSVVPPParam to QSVVPPContext
so that all QSV filters using QSVVPPContext may support async depth.
In addition, we may use QSVVPPContext as base context in other QSV
filters in the future so that we may re-use functions defined in
qsvvpp.c for other QSV filters.
This commit shouldn't change the functionality of vpp_qsv / overlay_qsv.

This is in preparation for reusing the code for other QSV filters. E.g.
deinterlacing_qsv may have an option array without format option

QSV filters may set this flag in preinit callback to turn on / off pass
through mode
This is in preparation for reusing the code for other QSV filters. E.g.
scale_qsv filter doesn't support pass through mode.

Set the expected default value for options in this callback, hence we
have the right values even if these options are not included in the
option arrray.
