`std::clamp` was introduced at 60a45d3aa3 but it caused a runtime
assertion failure on Windows that checks the low value of `std::clamp`
is not greater than the high value.
MbedTLS changed a lot of internals with their LTS version 3.6.0, which
are incompatible with the find module currently shipped with
OBS Studio.
The solution requires several changes to be applied at once:
* Rename the generated target name to MbedTLS::mbedtls to match the
name used by MbedTLS' own CMake package
* Update find module to use the updated target name(s)
* Set CMAKE_FIND_PACKAGE_PREFER_CONFIG to TRUE before trying to find
MbedTLS to ensure that CMake package files are used with priority
(Those are shipped only with MbedTLS 3.6.0 in obs-deps).
* A deprecation warning is emitted if the find module is used with
MbedTLS 3.6.0 available
This change enables loading scene collections from locations different
than OBS' own configuration directory.
It also rewrites profile management in the app to work off an in-memory
collection of profiles found on disk and does not require iterating
over directory contents for most profile interactions by the app.

This introduces a split of the current single ConfigFile instance for
all configuration into two separate instances.
The app config instance contains system-wide settings that mainly
concern the working of the app itself, whereas the user config instance
contains settings actually exposed to the user for the configuration.
When using the Auto-Configuration Wizard with the
Twitch service, testing for Enhanced Broadcasting would
always run, even if deselected. Add a conditional check
to only run the test if selected.
This doesn't generally make the speedtest work for Amazon IVS, since
most Amazon IVS channels will be disconnected if the bitrate being
sent exceeds the upper limit for that channel.
Introduce support for delivering BPM (Broadcast
Performance Metrics) over SEI (for AVC/H.264 and
HEVC/H.265) and OBU (for AV1) unregistered messages.
Metrics being sent are the session frame counters,
per-rendition frame counters, and RFC3339-based
timestamping information to support end-to-end
latency measurement.
SEI/OBU messages are generated and sent with each IDR
frame, and the frame counters are diff-based, meaning
the counts reflect the diff between IDRs, not the running
totals.
BPM documentation is available at [1].
BPM relies on the recently introduced encoder packet timing
support and the packet callback mechanism.
BPM injection is enabled for an output by registering
the `bpm_inject()` callback via `obs_output_add_packet_callback()`
function. The callback must be unregistered using
`obs_output_remove_packet_callback()` and `bpm_destroy()`
must be used by the caller to release the BPM structures.
It is important to measure the number of frames successfully
encoded by the obs_encoder_t instances, particularly for
renditions where the encoded frame rate differs from the
canvas frame rate. The encoded_frames counter and
`obs_encoder_get_encoded_frames()` API is introduced
to measure and report this in the encoded rendition
metrics message.

When a source file contains an explicit include with a filename
following the "moc_<actual-filename>.cpp" pattern, then CMake's
AUTOMOC generation tool will recognize the matching pair and generate
the replacement header file and add the required include directory
entries.
For all files which do contain Q_OBJECT or similar declarations but do
not have an explicit include directive, the global mocs_compilation.cpp
file will still be generated (which groups all "missing" generated
headers).
The larger this global file is, the more expensive incremental
compilation will be as this file (and all its contained generated
headers) will be re-generated regardless of whether actual changes
occurred.
This adds scrollbars to the preview, so users can move around the
preview without using the spacebar + clicking.

This fixes a memory leak introduced in [1] where a new QColor is not
