flash/stm32l4x: add support of STM32WLEx devices

Browse Source 
STM32WLEx devices are based on arm Cortex-M4 running at 48MHz,
contains a single bank of maximum 256 Kbytes of flash memory.

there is 3 variants with different Flash/RAM sizes:
  STM32WLE5JC : 256K/64K
  STM32WLE5JB : 128K/48K
  STM32WLE5J8 :  64K/20K

the work-area size is set to 20 kb to fit in STM32WLE5J8
