Duck Octagon V1 Configurator cleanup (#5957)

* Expand info.json formatting to one line per key

This is a white-space-only change. Make it easier for me to read the file.

* Make sure every key object has a label

Going to be using them shortly.

* Insert key identifiers from v1.h into info.json labels

Shows where each key is located in the switch matrix.

* Move K5O to its correct location on the top row

* Adjust white space in v1.h

At this point, the macros for LAYOUT and LAYOUT_75_ansi are 100% identical, except for their names.

* Redefine LAYOUT_75_ansi as an alias of LAYOUT

No need for two code blocks with the same data.

* Correct visual positioning in info.json

- move Pause 1u to the right
- move K5O to the top row, between Print Screen and Pause
- move Enter key 1u to the left and 1u wider (1.25u to 2.25u)

* Delete key identifiers from info.json labels

Don't need them anymore now that we know where everything is.

I'm calling K5O as ScrLk so it has a label, even though that's not actually what it is.

Also gave the Spacebar a label because I prefer when all the keys have labels.

* Enable 75_ansi Community Layout support

* Reassign layout macro as LAYOUT_75_ansi and delete macro alias

Configure the codebase so LAYOUT_75_ansi is the only layout macro available.

* Add key_count key to info.json data
