Reduce input sizes to 8 (to test that the function works with widths
smaller than the vector length) and 1920 (raising the largest input
size to improve benchmark results).
This commit also fixes the issue that the call to ff_sws_init_range_convert()
from sws_init_swscale() was not setting up the arch-specific optimizations.

For example, the default surface configuration on macOS is:

With HDR10 content and swapchain_colorspace_hint, the surface

Film grain support adds a huge amount of overhead to the H264Context
structure for a feature that is rarely used. On low end devices or
pages that have lots of media this bloats memory usage rapidly.
This changes the static film grain metadata allocations to be dynamic
which reduces the H264Context size from 851808 bytes to 53444 bytes.

And preserve the public SwsContext as separate name. The motivation here
is that I want to turn SwsContext into a public struct, while keeping the
internal implementation hidden. Additionally, I also want to be able to
use multiple internal implementations, e.g. for GPU devices.
This commit does not include any functional changes. For the most part, it is
a simple rename. The only complications arise from the public facing API
functions, which preserve their current type (and hence require an additional
unwrapping step internally), and the checkasm test framework, which directly
accesses SwsInternal.
For consistency, the affected functions that need to maintain a distionction
have generally been changed to refer to the SwsContext as *sws, and the
SwsInternal as *c.
In an upcoming commit, I will provide a backing definition for the public
SwsContext, and update `sws_internal()` to dereference the internal struct
instead of merely casting it.

Clarify the meaning of the default value, and how the '+' and '-'
prefixes work. Add more examples.
-stats:
Clarify that it appears as an "info"-level log.
-progress:
Add info about the "progress" key's value being "continue" or "end".
Add an example of logging to stdout.

Replacing the old sws_isSupported* API with a more consistent family
of functions that follows the same signature and naming convention,
including a placeholder for testing the color space parameters that
we don't currently implement conversions for.
These functions also perform some extra basic sanity checking.

Groups together all relevant color metadata from an AVFrame. While we could
use AVFrame directly, keeping it a separate struct has three advantages:
1. Functions accepting an SwsFormat will definitely not care about the
data pointers.
2. It clearly separates sanitized and raw metadata, since the function to
construct an SwsFormat from an AVFrame will also sanitize.
3. It's slightly more lightweight to pass around.
Move these into a new header file "utils.h" to avoid crowding
swscale_internal.h even more, and also to solve a circular dependency issue
down the line.

Ensure those bits are copied, which will result in the output being the same as
the input, where swscale set them to the equivalent of fully opaque.
