d4ab3df3 - [AArch64] Fix SVE scalar fcopysign lowering without neon. (#129787)

[AArch64] Fix SVE scalar fcopysign lowering without neon. (#129787) Without this we can try to generate invalid instructions or create illegal types. This patch generates a SVE fcopysign instead and use its lowering. BF16 is left out of the moment as it doesn't lower successfully (but could use the same code as fp16).
