Optimise cyclic value (#1607) 
* Updated ignore for hard link for CLion

* Initial working version

* Optimised advance template call

* Further optimsed advance

Updated docs and tests

* Moved comparison operators out of the class.

* Implement spaceship operator <=> for No-STL case (#1604)

This was disabled explicitly in recent commit
232c948674cff1b4b72c2d6b3acfa7342d096dd1 to prevent using
the <compare> header from STL.

Now, re-enabling by implementing an ETL version of it in compare.h

* Sponsorship message updates

* Fix duplicated check runs

* Refactored the advance function to fix issues with signed unsigned mod operations.

* clang-format

* Updated documentation for cyclic_value

* Modified code comments

* Fixed a logic issue in advance() where a less than maximum step from the minimum value for a cyclic value covering the full type's range would take the wrong logical path (Step would roll over), although calculating the correct result.

This could be cofusing to someone debugging cyclc_value.

* Added runtime ans static asserts for reverse ordered limts.

* clang-format

* Spelling fix 'fast' -> 'last'

* Code review updates

* clang-format

* Code review updates

* Code review updates
