[Keyboard] Alf X1.1 QMK Support (#5189)

* initial commit

* get rid of vanilla cookie cutter code  and replace with  more correct info

* edit config file for pins and switch matrix size

* turn on bootmagic lite, and backlight/rgb settings

* copy pasta switch matrix from noroads tool

* create an appropriate keymap (copy pasta)

* disable some features to decrease firmware file size

* add qmk configurator support

* add in support for caps lock, scroll lock, and num lock leds

# Alf X1.1

TKL Keyboard made by Alf

Keyboard Maintainer: [MechMerlin](https://github.com/mechmerlin)  
Hardware Supported: Alf X1.1 PCB  
Hardware Availability: [Massdrop](https://www.massdrop.com/buy/alf-studio-x1-1-custom-mechanical-keyboard-kit)

Make example for this keyboard (after setting up your build environment):

    make alf/x11:default

# Processor frequency.
#     This will define a symbol, F_CPU, in all source code files equal to the
#     processor frequency in Hz. You can then use this symbol in your source code to
#     calculate timings. Do NOT tack on a 'UL' at the end, this will be done
#     automatically to create a 32-bit value in your source code.
#
#     This will be an integer division of F_USB below, as it is sourced by
#     F_USB after it has run through any CPU prescalers. Note that this value
#     does not *change* the processor frequency - it should merely be updated to
#     reflect the processor speed set externally so that the code can use accurate
#     software delays.

# Input clock frequency.
#     This will define a symbol, F_USB, in all source code files equal to the
#     input clock frequency (before any prescaling is performed) in Hz. This value may
#     differ from F_CPU if prescaling is used on the latter, and is required as the
#     raw input clock is fed directly to the PLL sections of the AVR for high speed
#     clock generation for the USB and other AVR subsections. Do NOT tack on a 'UL'
#     at the end, this will be done automatically to create a 32-bit value in your
#     source code.
#
#     If no clock division is performed on the input clock inside the AVR (via the
#     CPU clock adjust registers or the clock division fuses), this will be equal to F_CPU.
