flash/stm32l4x: switch to to c loader instead of assembly loader

Browse Source 
switching to C loader instead of the assembly version will enhance readability
will reduce the maintenance effort.

besides the switch to C loader, we added a new parameters to the loader
like flash_word_size and flash_sr_bsy_mask in order to support properly
STM32U5x and STM32G0Bx/G0Cx in dual-bank mode.
