Kernel: Make i8042 controller initialization sequence more robust

Browse source 
The setting of scan code set sequence is removed, as it's buggy and
could lead the controller to fail immediately when doing self-test
afterwards. We will restore it when we understand how to do so safely.

Allow the user to determine a preferred detection path with a new kernel
command line argument. The defualt option is to check i8042 presence
with an ACPI check and if necessary - an "aggressive" test to determine
i8042 existence in the system.
Also, keep the i8042 controller pointer on the stack, so don't assign
m_i8042_controller member pointer if it does not exist.

For troubleshooting purposes, you can add the following command line arguments if you suspect our implementation fails to work with your hardware:
- `disable_physical_storage`
- `disable_ps2_controller`
- `disable_uhci_controller`
Because iPXE (unlike GRUB) doesn't support VESA VBE modesetting when booting a multiboot kernel,
