Help: Clarify behavior of path-based equality conditions

Browse Source 
The docs for if(PATH_EQUAL) did not mention the component-wise
nature of the checks. It also claimed no normalization was
performed, but multiple separators are effectively collapsed
(part of normalization). Improve the wording to clarify both of
these points.

Also update the corresponding description of cmake_path(COMPARE),
which had the same inaccuracy.

Fixes: #23758
