SDL normalizes the super/GUI modifier away, so adding a key with this modifier will overwrite the base, unmodified value.

- Use exact numerator/denominator from spec for CMTime to avoid rounding errors.
- Wrap frame rate setting in @try-catch to prevent crashes on strict drivers.

Don't disable this functionality when defining SDL_LEAN_AND_MEAN, but if you need to, you can define SDL_DISABLE_STB if you want to compile this out.

We have an implementation that uses 128-bit math and one that handles large values without it (thanks @jessechounard and @rabbit-ecl!)
Fixes https://github.com/libsdl-org/SDL/issues/15042
(cherry picked from commit 24404d9047)
V4L2 is able to advertise that a video device is able to display any frame
interval within a continuous range. SDL does not allow advertising this and
only exposes discrete frame intervals. To work around this, SDL attempted to
generate a subset of the range with a fixed interval. Unfortunately, the way
this was accomplish is inherently broken and led to attempting to allocate a
very large number of formats per resolution and colorspace. With the Magewell
Pro Capture HDMI, which can expose FRMSIZE_TYPE_CONTINUOUS as well, this can
expose a truly astronomical number of formats, exceeding 1 PB of RAM. This will
lead to an OOM kill for any process that tries to initialize the camera
subsystem.
This patch just tests to see if some common frame rates are within the
contiuous range and expose those. SDL still does not handle
FRMSIZE_TYPE_CONTINUOUS in a graceful way so it still uses over a gigabyte of
RAM for each possible combination of sizes, but with this patch it no longer
leads to an OOM kill. The API will need amending for proper support for both
continuous frame sizes and frame intervals.

This is only useful if the application knows to add the flag introduced by this
extension, and at that point the application can also include the extension
themselves.
Case in point: SDL_gpu_vulkan was already doing this!
