* remove K214 from LAYOUT_1065_ansi macro
Position K214 is only used by the ISO layout (as KC_NUHS); it doesn't get used here. Removing it so the layout macro matches the info.json layout data.
Also updates info.json to use human-friendly formatting.
* add layout macros
Adds:
- LAYOUT_1065_ansi_split_bs macro
- LAYOUT_1065_iso macro
- LAYOUT_1065_iso_split_bs macro
- `default_iso` keymap
* add LAYOUT_all macro
Adds LAYOUT_all macro and a `default_all` keymap.
This PCB is unusual in that the ANSI Backslash and ANSI Enter do not share their matrix positions with the Non-US Backslash or ISO Enter keys at all. This layout macro supports both the ANSI and ISO positions in one macro/keymap.
* Set bootloader to stm32-dfu for STM32F303
* Set bootloader to stm32-dfu for STM32F0x2
* Set bootloader to stm32-dfu for STM32F4x1
* Set bootloader to stm32duino for sowbug
* Delete redundant bootloader_defs headers
* Add some missing MCU name comments
* Move APM32 dfu-suffix overrides underneath bootloader
* Remove redundant STM32_BOOTLOADER_ADDRESS defines/rules
