This commit rounds the timestamp to the integer multiple of fps_den.
Prior to this change, since the timestamp in MFX is defined in units of
90 kHz, timestamps for 60000/1001 fps is not accurately expressed. Also
the encoder sometimes returns the decode time stamp slightly off.
Hence, the timestamp in OBS becomes not a multiple of fps_den after
converting back from the timestamp in MFX.
Status output related to OBS configuration is prefixed with the string
"OBS" and added padding for enabled and disabled features. This padding
was not aligned between platforms.
By moving the padding and prefix decoration into its own function,
both elements are controlled in a single place. CMake scripts were
changed to use this new function `obs_status` instead of using CMake's
`message` function directly.
_dx9_simple_free already frees this pointer. I don't think this code
path is currently reachable, but it should probably still be fixed.

As Intel continues to add discrete graphics cards, maintaining a long
list of discrete device IDs to check against isn't wise. When i+I
platforms are detected, default to integrated graphics.
Intel committed an NDA disclaimer on each source file. The stated
intention was that the NDA "added to OBS doesn't apply to open source
code once it's been accepted by the community. You can remove it for
your modifications". This quote is from an email chain involving
Intel's legal team and developers. The NDA in the source files
mistakenly triggers source code scanners that look for license
violations. I have removed the comments that contain the NDA.
Unfortunately these encoders tend to crash or freeze after after
multiple bitrate changes. Users with dynamic bitrate enabled
experience a random encoder freeze which manifests as OBS dropping to
0kb/sec and disconnecting and it's not at all obvious that dynamic
bitrate is the cause. Disable it for now until we can figure out if
there is any workaround or bug on our end.
Fix for an issue found where new "Latency" and "Subjective Video
Enhancement" options where always using default settings even after
being changed in UI. This issue was introduced when mapping old QSV
settings to new ones.
Simplify UI options by combining LookAhead Depth and Async Depth into
latency mode option. Ultra-low, low, and normal will set these two
encode parameters accordingly.

Enables a pipeline for texture-based encoding with QSV. Utilizes OBS
NV12 output for encode to avoid offloading them from GPU, which will
increase performance. The option to select old QSV pipeline still
remains and will fallback if new pipeline fails.
PR #1937 (commit b9ad1ce) added QSV target usage options, but there was
a comma missing between two of the array entries. This resulted in
"faster" and "veryfast" becoming "fasterveryfast", which is not valid.
Code style changes were required by .clang-format.
Add the option to enable custom quantization matrix for game streaming
on ICL for better subject quality. Feature is only supported with AVC
high profile, so added function to detect when QSV profile is modified
and hide or show CQM UI option accordingly. Also, increase SPS/PPS
buffer sizes since matrix is stored in SPS/PPS.
