BaseTools/GenFw RVCT: fix relocation processing of PT_DYNAMIC sections
Unlike GNU ld, which can be instructed to emit symbol based static
relocations into fully linked binaries using the --emit-relocs command
line switch, the RVCT armlink tool can only emit dynamic relocations
into the PT_DYNAMIC segment.
This has two consequences
. we can only identify absolute relocations, so there is no way to fix
up relative relocations between sections, or check their validity in
the PE/COFF layout
. the r_offset fields of the PT_DYNAMIC DT_REL entries are relative
either to the base of the image or to any of its segments but *not* to
the base of the input section that contains the location they refer
to, and converting them to PE/COFF image offsets is non-trivial unless
the sections are laid out in the same way in the ELF and PE/COFF
versions of the binary.
There is really only one way to deal with this, and that is to require
that the ELF and PE/COFF versions of the binary are identical in memory.
So enforce that in the code.
Also, fix the utterly broken relocation fixup code that dereferences
ELF32_R_SYM(r_info) both as a 1-based program header index and a 0-based
section header index. If this code ever produced working binaries, it
was purely by chance.

BaseTools RVCT: use scatter file to enforce minimum section alignment
Up until SVN r18540, GenFw created invalid PE/COFF binaries for the ARM
architecture, by allowing PE/COFF .data sections to appear at offsets
that were not aligned to the global PE/COFF section alignment. The
reason for this was that the relocation metadata emitted by RVCT's
armlink only contains dynamic absolute relocations, so it is impossible
to recalculate relative relocations between .text and .data, and so the
relative offset between the two needs to be preserved.
Since r18540, we do align .data to the PE/COFF section alignment,
resulting in potentially corrupt PE/COFF binaries unless .data happens
to appear at a 32-byte aligned offset. So let's introduce a RVCT scatter
file that sets this alignment for the ELF .data section (and subsequent
.bss section).
At the same time, set the start offset to 0x220 bytes (which is the size
of our 32-bit PE/COFF header) so that the memory layouts are identical
between ELF and PE/COFF. Also add a 4 KB aligned version that can be
used to build DXE_RUNTIME_DRIVER modules with runtime memory protection
