Target/X86: Add explicit Win64 and System V/x86-64 calling conventions. Summary: This patch adds explicit calling convention types for the Win64 and System V/x86-64 ABIs. This allows code to override the default, and use the Win64 convention on a target that wants to use SysV (and vice-versa). This is needed to implement the `ms_abi` and `sysv_abi` GNU attributes.

[AArch64] Extend CallingConv::X86_64_Win64 to AArch64 as well Rename the enum value from X86_64_Win64 to plain Win64. The symbol exposed in the textual IR is changed from 'x86_64_win64cc' to 'win64cc', but the numeric value is kept, keeping support for old bitcode.
