* Add support for MKS Robin TFT display

- Add support for MKS Robin TFT display and encoder for MKS Robin board.
- Generic 128x64 UI with x2 upscale is used (for now).
- Tested on MKS Robin TFT V2.0 with ST7789V controller.

Move `watchdog_reset` from `.h` to `.cpp` to eliminate the need to include `MarlinConfig.h` in a HAL-related file.

Implement initial support for MKS Robin (STM32F103ZET6) board.
Custom build script is used to generate encrypted firmware compatible with original MSK Robin bootloader (i.e. safe firmware update from SD card and possibility to go back to original close-source firmware).

* Make CardReader a static class
* Make CardReader flags into bitfields

In reference to #11000

* Apply #pragma once in headers
* Adjust some thermistors formatting
* Misc cleanup and formatting

STM32 can reuse JTAG and SWD pins separately. Add `DISABLE_DEBUG` option to disable both interfaces and retain `DISABLE_JTAG` to disable JTAG only.

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.

Implement servo support for STM32F1. Original code was incomplete and depended on Servo library from stm32duino which conflicts with `module/servo.h`.

The `binary.h` file required by `lcd/dogm/dogm_bitmaps.h` is not present in stm32duino environment. Binary macros are defined in `bit_constants.h` in stm32duino framework.

Fix "SD init fail" problem for STM32F1 caused by incorrect SS pin state and incorrect SPI mode. Issue #11225

- Clean up the API to use a `static` class instance to adhere to Marlin convention
- Add `const` position data access for read/write
- Add Storage capacity to the interface

The current Marlin implementation relies on a timer interrupt to start the ADC conversion and read it. However in some circumstances the interrupt can be delayed resulting in insufficient time being available for the ADC conversion. This results in a bad reading and false temperature fluctuations. These changes make sure that the conversion is complete (by checking the ADC hardware via the HAL) before reading a value.

Always honor minimum period on stepper pulse generation, and fix timing calculations

- Enable / disable interrupts with `__iSeiRetVal` / `__iCliRetVal`
- Add STM32F1 to Travis CI tests

* Misc fixes and improvements

- Get rid of most critical sections on the Serial port drivers for AVR and DUE. Proper usage of FIFOs should allow interrupts to stay enabled without harm to queuing and dequeuing.
  Also, with 8-bit indices (for AVR) and up to 32-bit indices (for ARM), there is no need to protect reads and writes to those indices.
- Simplify the XON/XOFF logic quite a bit. Much cleaner now (both for AVR and ARM)
- Prevent a race condition (edge case) that could happen when estimating the proper value for the stepper timer (by reading it) and writing the calculated value for the time to the next ISR by disabling interrupts in those critical and small sections of the code - The problem could lead to lost steps.
- Fix dual endstops not properly homing bug (maybe).

* Set position immediately when possible

- Also implemented real endstop reading on interrupt.

Use macros that explicitly avoid double-evaluation and can be used for any datatype, replacing `min`, `max`, `abs`, `fabs`, `labs`, and `FABS`.
