Separate remote upload and run configuration

### Description

Currently the FTP/SFTP remote upload configuration is part of the "Run configuration".
I propose to separate this out so that remote uploads can be done at any time and independent from the choosen run configuration

### Use case/motivation

I am using both the PHP built-in webserver and a webserver running on a remote server for PHP development. It is very inconvenient that I cannot use the local, built-in webserver and still be able to easily upload files to the remote system without always having to change the run configuration.
I see uploading and run configuration as separate things that should be configured independently.

No

Start by locating the NetBeans PHP run-configuration code and its FTP/SFTP upload settings. Trace how upload settings are currently tied to the selected run configuration, then define the independent configuration flow. Done means users can upload to the remote system while using a different local run configuration.
