refactor: split server and inputs into their own groups

[Hazer]

Description

Breaking the project in smaller pieces will make the project easier to contribute and maintain in the future, it's not a major rewrite, just moving files or splitting a single file into many without major refactors.

Moves the following files to the server folder:

confighttp.cpp
confighttp.h
crypto.cpp
crypto.h
httpcommon.cpp
httpcommon.h
network.cpp
network.h
nvhttp.cpp
nvhttp.h
rtsp.cpp
rtsp.h
upnp.cpp
upnp.h

Moves the following input to the input folder and split it into:

common.cpp
common.h
gamepad.cpp
gamepad.h
init.h
keyboard.cpp
keyboard.h
mouse.cpp
mouse.h
pen.cpp
pen.h
processor.cpp
processor.h
touch.cpp
touch.h

Since this is touching every source file in the project, maybe it's a good opportunity to take care of this as well? #2186

@ReenigneArcher I was trying to avoid as much conflict as possible, but can be done, or in a future PR too. Can we force the rules to be different only for /input and /server subfolders? This way I could start migrating piece by piece

[ReenigneArcher]

Due to recent changes to the docs, all the doc changes can be dropped from this PR.
