Add flag to disable automatic clipboard updates

[aidik]

• I have checked that a similar feature request does not already exist.

Describe the solution you'd like
It would be nice to have control over the automatic clipboard population on the host.
scrcpy -s abcd1234 --clipboard-copy false

Describe alternatives you've considered
Running scrcpy in a VM. Doable, but seems like overkill for something that can be potentially just one if clause.

Additional context
It will improve quality of life during passive control over the scripted tasks. Limiting disturbations to other work.

I would also like this feature.

Is your feature request related to a problem? Please describe.
I am currently running the following setup:
computer A <-- Barrier --> computer B <-- scrcpy--> phone
with the phone and computers also connected via KDEConnect.

Attempting to copy (ctrl+c) on the computer often fails unless I spam the command.

Describe the solution you'd like
I would like to disable clipboard copy in scrcpy via command line to avoid the conflict.

Describe alternatives you've considered
Disabling clipboard sync on KDEConnect or disconnecting the phone from scrcpy solves the issue. Disabling clipboard sync via KDEConnect needs to be done by hand for each synced computer, which is more work to do each time I connect/disconnect my phone from scrcpy. Barrier clipboard sync needs to remain for other computers.

#2817 adds an option --no-clipboard-autosync. Please test it 😉
