  [NFC][AsmPrinter] Refactor AsmPrinter and AArch64AsmPrinter to prepare for jump table partitions on aarch64 (#125993)

With
https://github.com/llvm/llvm-project/commit/3feb724496238ce10d32e8c2bd84b4ea50f9977e,
AsmPrinter can place jump table entries into `.hot` or `.unlikely`
prefixed data sections. This change refactors AsmPrinter and
AArch64AsmPrinter to prepare for the aarch64 port.

* Before this patch, the AsmPrinter class exposes `emitJumpTableInfo` as
a virtual method, and AArch64AsmPrinter overrides `emitJumpTableInfo`
for jump table emission.
* After this patch, both AsmPrinter and AArch64AsmPrinter shares
`AsmPrinter::emitJumpTableInfo`, and class-specific code are moved
inside each class's `emitJumpTableImpl` respectively.

This is a follow-up of https://github.com/llvm/llvm-project/pull/125987,
and https://github.com/llvm/llvm-project/pull/126018 implements the port
for aarch64.
