OvmfPkg: LockBox: use SMM stack with -D SMM_REQUIRE 

During DXE, drivers save data in the LockBox. A save operation is layered
as follows:

- The unprivileged driver wishing to store data in the LockBox links
  against the "MdeModulePkg/Library/SmmLockBoxLib/SmmLockBoxDxeLib.inf"
  library instance.

  The library allows the unprivileged driver to format requests for the
  privileged SMM LockBox driver (see below), and to parse responses.

  We apply this resolution for DXE_DRIVER modules.

- The privileged SMM LockBox driver is built from
  "MdeModulePkg/Universal/LockBox/SmmLockBox/SmmLockBox.inf". This driver
  has module type DXE_SMM_DRIVER and can access SMRAM.

  The driver delegates command parsing and response formatting to
  "MdeModulePkg/Library/SmmLockBoxLib/SmmLockBoxSmmLib.inf".

  Therefore we include this DXE_SMM_DRIVER in the build, and apply said
  resolution specifically to it.

  (Including the driver requires us to resolve a few of other library
  classes for DXE_SMM_DRIVER modules.)

- In PEI, the S3 Resume PEIM (UefiCpuPkg/Universal/Acpi/S3Resume2Pei)
  retrieves data from the LockBox. It is capable of searching SMRAM
  itself.

  We resolve LockBoxLib to
  "MdeModulePkg/Library/SmmLockBoxLib/SmmLockBoxPeiLib.inf" specifically
  for this one PEIM.
