HAL general support for DISABLE_JTAG option (#11211)

Browse source 
Some STM32-based boards may use multiplexed JTAG pins as IO. Up to now the `DISABLE_JTAG` option (defined in pins files) was only supported for AT90-based boards. This commit generalizes the code and adds support for boards based on STM32F1 and STM32F4.
