TracyConfig.cmake now sets TRACY_VERSION_STRING and a
TracyConfigVersion.cmake is generated and installed, so
find_package(Tracy X.Y CONFIG) works against installed trees.
Compatibility mode is SameMinorVersion: for a 0.x project the minor
version is the compatibility unit, and consumers who need to pin the
exact version can use find_package(... EXACT). SamePatchVersion is
not an option - it requires CMake 4.4 while the project minimum is
3.13.
