When libluv is built statically it appends an '_a' suffix to the library name. This affects CMake's ability to find the bundled version of libluv (which is built statically) when there is a dynamic version of the library also built on the system, which does not have the '_a' suffix. Prioritize searching for 'libluv_a' first before falling back to 'libluv'. This will ensure the bundled version of libluv is always found first before any system versions of libluv. In cases where we are not using bundled libraries, CMake will still safely fall through to finding 'libluv' since package managers do not typically provide static system libraries.
