Add do while (0) to Id and ID macros

[hugobpontes]

The ID and Id macros were giving me syntax warnings saying a ";" was missing anytime I used them, which was very annoying as in my IDE (STM32Cube) it filled the code (even other lines) with underlining, making it a bit unreadable.
To fix it I added do {} while (0) to those to macros, and the error disappeared.
I suppose it's possible that other people, especially in other IDEs were not getting this warning but I think my proposed changes only improve the code for people with the same problem as me and will not affecting others.

If you wish to make any change or want me to make any change before merging, feel free to!

Thanks for the pull request, Hugo! I recommend to use the macros trice, Trice and TRice instead of using TRICE( id(n), TRICE( Id(n) and TRICE (ID(n). The TRICE macros are inlining code each time you use them causing bigger firmware images when you use them many times. The trice, Trice and TRice macros are function calls.

I wanted a 32 bit timestamp and used trice, so trice(iD(n)) was generated, but I got no timestamp. When I quickly looked in trice.h I assumed only ID would give me a 32-bit timestamp, so when I used TRICE and TRICE(ID(n)) was generated and worked, I assumed TRICE and ID was the way to go.
After seeing your comment, I tested with TRice(iD(n)) and it works as well (of course :) ), so thank you for the tip!
