ArmVirtPkg/ArmVirtPrePiUniCoreRelocatable: deal with relaxed XIP alignment
Commit b89919ee8f8c ("BaseTools AARCH64: override XIP module linker
alignment to 32 bytes") updated the various AARCH64 toolchain definitions
to allow SEC, PEI_CORE and PEIM modules to be built with minimal alignment
requirements even when using the AArch64 small code model which normally
requires 4 KB section alignment.
This involves conversion of ADRP instructions into ADR instructions, which
can only be done reliably if the ELF and the PE/COFF sections appear at
the same offset modulo 4 KB.
The ArmVirtPrePiUniCoreRelocatable linker script did not yet take this
into account, so update it by starting the .text section at the next
appropriately aligned offset PECOFF_HEADER_SIZE bytes into the image.
