vmware-vmx: cd_files, cd_content not working for ARM guests

[eszense]

Description

Current default for Packer configured CD (cd_files, cd_content) is to use the IDE adapter. However, this would not work for ARM guest since IDE is not supported by VMware in these guests (https://kb.vmware.com/s/article/90364). It appears desirable to change the default to SATA for ARM guest. There is currently no config to change the cdrom adapter for vmware-vmx because the cdrom_adapter_type config is only exposed in vmware-iso but not vmware-vmx

Use Case(s)

cloud-init for ARM guest on VMware Fusion on all Apple Silicon host

Potential solution when generating the VMX:

func DefaultDiskAndCDROMTypes(diskAdapterType string, cdromAdapterType string) DiskAndCDConfigData {
	diskData := DiskAndCDConfigData{
		SCSI_Present:         "FALSE",
		SCSI_diskAdapterType: "lsilogic",
		SATA_Present:         "FALSE",
		NVME_Present:         "FALSE",

		DiskType:                   "scsi",
		CDROMType:                  "ide",
		CDROMType_PrimarySecondary: "0",
	}

   // If arm64, default to sata.
	if runtime.GOARCH == "arm64" {
		diskData.CDROMType = "sata"
	}

   // rest of function...
