[Keyboard] mlego fix product id and sync oled code (#16237)

* sync oled code over the keymaps

* put different product ids

* put different product ids for the rest

* put different product ids for the rest

* try to reduce code duplication

* make ifdefs nice and correct

* move the leds code out of keymap

* try to reduce code duplication

* move the rgb code outside the keymaps for reuse

* Update keyboards/mlego/m65/m65.c

* move more code outside keymaps for reuse

* add few more xps

* add mic mute

* update to new name of macros for reset

* style for matrix

* clean split

* use tinyuf2 as bootloader

* Update keyboards/mlego/m65/rev4/rules.mk

Co-authored-by: Ryan <fauxpark@gmail.com>

* radionalise product id and device version

* add tinyuf2 as default bootloader for stm32f4

* update tinyuf2

* update tinyuf2 and via. f411 remove tinyuf2 since is not really working. make the config more conditional

* sync the keymap with default

* revert via non building with gcc 11
