Add bash completion script to scrcpy installation (script included here)

Is your feature request related to a problem? Please describe.
Related to the completion of device id for when you are using multiple devices.

Describe the solution you'd like
When typing scrcpy -s + TAB_KEY there is no bash completion for the device id. There is already a bash script for adb. What I've done is copying the adb script and made some modifications to it.

Describe alternatives you've considered
The current alternative is copying devices ids manually or typing adb -s + TAB_KEY, then changing the adb command to scrcpy

Additional context
I've attached the script. Just EXTRACT IT and copy it to /etc/bash_completion.d/ and enjoy!
scrcpy.tar.gz
It would be very nice if this script(or a similar/cleaner version) could be installed automatically with the scrcpy installation.

scrcpy already has bash completion and zsh completion scripts.

I agree that they should be improved so that the -s option is completed by the available devices exposed by adb devices.

Thanks. I've made a pull request with the modification in the default bash_completion script.
