payloads/external/iPXE: Add more Kconfig options

Add two now options:
* Disable the promt "Press Ctrl+B for the iPXE command line..."
Add a boolean that disable the initial 2 second timeout.

* Include a script that is executed instead of showing a shell
Allows to add a script that will be included into the iPXE ROM.

Tested on Lenovo T500.
