43bf33e791 Optimise usage of code_value() 
code_value() is float but in some cases we can save memory when the expected output is only 1 or 2 bytes.

Changes save 182 bytes of flash memory on my end.

e525bcb7f5 Optimise lcd_selftest_screen input parameters and return type 
* _progress_scale is max 3 so it can be uint8_t
* _progress is max 6 so it can be uint8_t
* Change _delay type to uint16_t to be explicit

Changes save 102 bytes of flash memory (Arduino IDE 1.8.19)

53dfcf9d6f Optimise if-statments in world2machine_clamp 
Only one of the statements can be true: tmpx < X_MIN_POS or tmpx > X_MAX_POS.
So we can be a little bit smarter here and skip the second if statement if the first was true.

This saves 6 bytes of flash memory and potential some clock cycles

581188ce2c Fix an issue found in code review 
Unfortunately this increases flash usages by 212 bytes (same usage as in current release) It seems it is most memory effcient to use int16_t (int). int8_t requires more memory.
