This commit ports the NEON square-root intrinsics (vsqrt, vsqrtq) for floating-point types to the pragma-based framework on aarch64. By moving these intrinsics into this unified system, GCC can manage their lowering and optimization more consistently. The direct function definitions in arm_neon.h are removed, and new function bases and definition groups are added in aarch64-neon-builtins-base.cc and .def. A new test case is included to verify the correct functioning of these ported square-root operations.
