feat: add support for dynamic directpath i/o

[kshivakumar-nvidia]

Description

As a part of the Assignable Hardware framework in vSphere 7, Dynamic DirectPath I/O is introduced. When configuring a virtual machine to use a PCIe device using Dynamic Direct I/O path, enables the Assignable Hardware intelligence for passthrough devices. No longer is the hardware address of the PCIe device directly mapped to the virtual machine configuration file (the .vmx file). Instead, the attributes, or capabilities, are exposed to the virtual machine.

Example

source "vsphere-iso" "example" {
  vcenter_server       = var.vsphere_server
  username             = var.vsphere_username
  password             = var.vsphere_password
  datacenter           = var.vsphere_datacenter
  cluster              = var.vsphere_cluster
  datastore            = var.vsphere_datastore
  network              = var.vsphere_network
  iso_paths            = [var.iso_path]
  iso_checksum         = var.iso_checksum
  iso_checksum_type    = "sha256"
  ssh_username         = var.ssh_username
  ssh_password         = var.ssh_password
  guest_os_type        = "windows9Server64Guest"
  disk_controller_type = "pvscsi"
  disk_size            = "60000"
  vm_name              = "my-vm"
  floppy_files         = ["path/to/floppyfile.txt"]
  pci_passthrough_allowed_device {
    "vendor_id": "8086",
    "device_id": "100e",
    "sub_device_id": "8086",
    "sub_vendor_id": "100e"
  }
}

Hi @kshivakumar-nvidia there has been no updates on this PR since we last reviewed. I'm going to close it as it has become stale. If you find that you want to continue adding support for DirectPath please rebase your branch onto the latest main and update the PR and reopen.

Thanks again for the contribution.

[tenthirtyam]

Reopened and rebased.
