8a2642cb - [AArch64][llvm-mca] Add old Cyclone instruction tables for reference (#172652)

[AArch64][llvm-mca] Add old Cyclone instruction tables for reference (#172652) This patch adds static instruction tables tests for the old Cyclone scheduling model bounded to `-mcpu=apple-m1`, for the sake of a reference. It creates a new `llvm/test/tools/llvm-mca/AArch64/Apple` directory, moves a Cyclone test there, and adds 2 tests `basic-instructions` and `neon-instructions` from Neoverse with reusable inputs (in addition to Neoverse, we also match stderr output of llvm-mca for instruciton warnings).
