[Keymap] Revamp spidey3 userspace and keymaps (#11768)

* Don't block keys during startup animation

* More refinements related to startup and debug state

* restore key logging

* some cleanup on scan rate reporting

* trim some fat

* better lighting to indicate jumped to bootloader

* use eeprom for state restoration

* a little reorganization

* report version immediately when turn on debug

* hold-to-adjust for hue, sat, val

* cformat

* reorg rules.mk settings, fix compile with CONSOLE_ENABLE=no

* simplify spidey3 userspace

* NULL in layer list caused buggy behavior

* more bugfix

* update numpad layout to match matt30 MT3 /dev/tty keycaps

* swap emdash and endash

* map shift+backspace to delete

* removing NO_ACTION_ONSHOT makes the firmware SMALLER ?!

* cformat

* improve spi_glow

* disable shift-backspace = delete by default
