Help: Document CMAKE_UNITY_BUILD_RELOCATABLE variable

Browse Source 
In commit 84996a65aa (Unity: Add option to use relative paths for unity
files, 2024-10-15, v4.0.0-rc1~637^2) we added support for this variable
to initialize the `UNITY_BUILD_RELOCATABLE` target property, but forgot
to document it.

Issue: #26352

CMAKE_UNITY_BUILD_RELOCATABLE
-----------------------------
.. versionadded:: 4.0
This variable is used to initialize the :prop_tgt:`UNITY_BUILD_RELOCATABLE`
property of targets when they are created. Setting it to true causes
sources generated for :variable:`CMAKE_UNITY_BUILD` to ``#include`` the
original source files using relative paths where possible.
