Turn device screen off _after_ everything has been set up
Sometimes it can take quite a while for everything to get set up and the screen to appear.
Note:
Intentionally kept the double if construct so it matches the previous blocks.

I merged the conditions in a single if, rebased on dev, and adapted the commit message to respect the 50-72 rule.
Please check before I merge: pr3902

Checked and it works fine - as intended.
(Under some special conditions there is sometimes still quite a gap between when the device screen is turned off and the scrcpy screen appears, but I suspect it would be too complicated to turn off the device screen even later.
The gap is much shorter with this fix, though, so time to let got of some perfectionism...)

Weird. How long? Can you reproduce a starting delay without turning the screen off? With another encoder (see scrcpy --list-encoders)? With another device? With another computer?
It's most likely a macOS issue, or maybe how some other programs handle OpenGL or Metal under macOS. When I have many windows with many tabs open in Safari (or other browser), some programs that want to use OpenGL take a long time to start. It seems like they're fighting over resources.
Not specific to scrcpy, so no worries. That's the background of this patch, with which it's a lot better.
If I shut down the browser, startup is fast.
And without any gap with this patch.
Anyway, here are timings with the different encoders, as requested, with many browser windows and tabs open in Safari:

This is on macOS Catalina (10.15.7) MacBook Pro 2.5 GHz Quad-Core Intel Core i7 NVIDIA GeForce GT 750M
Logged the startup without the macOS OpenGL core profile patch, just to make sure that it isn't adding to the startup time, and the timing is approximately the same. Sometimes it is even quite a bit longer, but that is probably macOS busy with something else.
Here is a run without the OpenGL core profile patch and with Safari open with a lot of windows and tabs:

Anyway, nothing to worry about. I don't see the long delay as a scrcpy issue.
And without
--render-driver=opengl?
Good point. Similar delays.

macOS seems to be quite tricky to get to behave when setting up OpenGL/Metal.
I have now tried some examples both from SDL and GLFW, and the setting up and removal of the OpenGL context makes the whole system stagger. Even more during teardown than setup actually. For example, if audio is playing, it stutters.
So this behaviour is not specific to scrcpy.
So far, the only program I have found that behaves well is mpv.
Just for comparison - and maybe inspiration - here is an example of
mpv playing the first half second of a video (with lots of windows
and tabs in Safari):

The whole setup, playing, and teardown is done in three quarters of a second. Without any disruption to any other program running. Hmm.
Possibly an issue with your graphics drivers, since apparently it does not happen for many users (nobody ever reported such a delay).
Maybe others don't have hundreds of tabs open in Safari... ;)
Anyway, it's not an issue with normal scrcpy use, since it's fine once it's running.
Only a bit of a nuisance when recompiling/restarting when "developing".
In any case, it can be merged (moreover if something fails to start, it's better if the device is not turned off for nothing): 798dfd240e53e964094c656f4e365f0cef33b943
