Allow changes to PPTT test table, preparing for adding identical

the system.

Per ACPI 6.5 Table 5.158: Processor Structure Flags, the identical
implementation flag indicates whether all the children processors
of this node share the same identical implementation revision.
Currently Linux support parsing this field [1] and maybe used to
identify the heterogeneous platform. Since qemu only support
homogeneous emulation, set this flag for all the processor node
to indicates the facts when building the PPTT table. Node leaf
is an exception since spec says this flag should be ignored
on leaf nodes by OSPM.

Currently we build the PPTT starting from the socket node and each
socket will be a separate tree. For a multi-socket system it'll
be hard for the OS to know the whole system is homogeneous or not
(actually we're in the current implementation) since no parent node
to telling the identical implementation informentation. Add a
root node for indicating this.

Update the ACPI tables according to the acpi aml_build change, also
empty bios-tables-test-allowed-diff.h.
The disassembled differences between actual and expected PPTT shows
below. Only about the root node adding and identification flag set
as expected.
