BaseTools/GenFw: ignore dynamic RELA sections
When building PIE (ET_DYN) executables, an additional RELA section is
emitted (in addition to the per-section .rela.text and .rela.data sections)
that is intended to be resolved at runtime by a ET_DYN compatible loader.
At the moment, due to the fact that we don't support GOT based relocations,
this dynamic RELA section only contains relocations that are redundant,
i.e., each R_xxx_RELATIVE relocation it contains duplicates a R_xxx_xx64
relocation appearing in .rela.text or .rela.data, and so we can simply
ignore this section (and we already ignore it in practice due to the fact
that it points to the NULL section, which has the SHF_ALLOC bit cleared).
For example,
Section Headers:
[Nr] Name Type Address Offset
Size EntSize Flags Link Info Align
[ 0] NULL 0000000000000000 00000000

Relocation section '.rela.data' at offset 0xaf00 contains 64 entries:

...
Relocation section '.rela' at offset 0x8a10 contains 64 entries:
Offset Info Type Sym. Value Sym. Name + Addend
000000004800 000000000008 R_X86_64_RELATIVE 419b
000000004808 000000000008 R_X86_64_RELATIVE 41a3
000000004810 000000000008 R_X86_64_RELATIVE 41b9

000000004828 000000000008 R_X86_64_RELATIVE 41ff
...
Note that GOT based relocations result in entries that *only* appear in the
dynamic .rela section and not in .rela.text or .rela.data. This means two
things if we intend to add support for GOT based relocations:
- we must check that a dynamic RELA section exists;
- we must filter out duplicates between .rela and .rela.xxx, to prevent
emitting duplicate fixups into the PE/COFF .reloc section.
