StandaloneMmPkg: Introduce a PCD to disable shadow boot FV
On some Arm platforms the boot firmware volume passed in the HOB
by the secure world firmware (TF-A) is never freed and is always
mapped as read-only.
On such platforms the heap memory can be saved by disabling the
shadow copy of the boot firmware volume. This is useful as on
some platforms the amount of memory available is limited.
Therefore, introduce a PCD PcdShadowBfv that platforms
can configure to disable the shadow boot FV. This PCD is set to
TRUE by default.
