[AArch64] NFC: Make some AArch64-SVE LoopVectorize tests generic.
This change moves most of `sve-inductions.ll` to non-AArch64 specific LV tests using the `-target-supports-scalable-vectors` flag, because they're not explicitly AArch64-specific. One test builds on AArch64-specific knowledge regarding masked loads/stores, and remains in sve-inductions.ll.
