Make STM32F412xE targets build ...

Trying to inherit the STM32F412xE target makes the linker fail, since
__CRASH_DATA_RAM_START__ is not present. Comparing LD scripts with the
STM32F412xG (which has active targets) it seems that the xE variant has
missed some updates somewhere. Since the LD scripts are otherwise
identical, copying the (working) ones from STM32F412xG seems to do the
trick.

Also added flash_data.h which was missing and needed here and there
(copied from xG and updated to fit the xE flash layout).

STM32: increase i2c slave rx limit. ...

Use uint16_t variables for i2c slave_rx_buffer_size and slave_rx_count
variables. This allows to receive more than 255 bytes in slave mode. The
bytes are received one by one in slave mode so there are no hardware
limitations forcing a 1 byte rx count limit.

This commit fixes the i2c driver issue reported in the below link:
https://github.com/ARMmbed/mbed-os/issues/13967 on STM32F4xx platform.

The data type of XferOperation has been changed from uint8_t to uint32_t
so that it can hold a 32bit value (for example: I2C_OTHER_FRAME or
I2C_OTHER_AND_LAST_FRAME).
