Fix(cmake): CMake doesn't find system installed SPIRV-Headers (#5422)

Browse Source 
To build repository version from sources current cmake require
to explicitly clone SPIRV-Headers repository to directory named
'external' with fixed name 'spirv-headers'.
This is a behavior which doesn't support searching global headers and
also CMAKE_PREFIX_PATH which makes development in some environments
less convenient than it should be.
The commit fixes this issue with keeping previous clone option intact.
