EmulatorPkg: Fix VS20xx IA32 boot failure 

https://bugzilla.tianocore.org/show_bug.cgi?id=2056

The IA32 build of the EmulatorPkg for VS20xx does not boot
because the default value of PCD PcdPeiServicesTablePage
rarely succeeds to be mapped on IA32 Windows Host Environments.
Change the DEC default value for this PCD to a value that
is compatible with Windows and POSIX host environments for
IA32 and X64.  For IA32 builds, this 64-bit PCD is truncated
to a 32-bit value.

PcdPeiServicesTablePage is changed from 0x1003000000 to
0x1013000000.  With this new value, no boot failures are
observed.  However, the use of this hard coded value can
potentially cause a boot failure if this address specified
by the PCD is already allocated in the user process.
