Mostly refactoring.
Rename original stm32x_write_block() to stm32x_write_block_async()
as it uses target async algo.
Introduce new stm32x_write_block() and move slow, host controlled
fallback flash write there.
The change allows stm32x_write_options() to use slow flash write fallback.
While on it rename variables where halfword count is stored.
