BaseTools/GenFw: Parse IBT/BTI support status from ELF note
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4405
When performing ELF to PE/COFF conversion, parse any notes sections to
decide whether the image supports forward CFI landing pads. This will be
used to set the associated DllCharacteristicsEx flag in a subsequent
patch.

BaseTools/GenFw: Add DllCharacteristicsEx field to debug data
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4405
The PE/COFF spec describes an additional DllCharacteristics field
implemented as a debug directory entry, which carries flags related to
which control flow integrity (CFI) features are supported by the binary.
So let's add this entry when doing ELF to PE/COFF conversion - we will
add support for setting the flags in a subsequent patch.

MdePkg/PeCoffLib: Capture DLL characteristics fields in image context
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4405
When loading a PE/COFF image, capture the DLL characteristics fields of
the header into our image context structure so we can refer to them when
mapping the image.

MdeModulePkg: Enable forward edge CFI in mem attributes table
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4405
The memory attributes table has been extended with a flag that indicates
whether or not the OS is permitted to map the EFI runtime code regions
with strict enforcement for IBT/BTI landing pad instructions.
Given that the PE/COFF spec now defines a DllCharacteristicsEx flag that
indicates whether or not a loaded image is compatible with this, we can
wire this up to the flag in the memory attributes table, and set it if
all loaded runtime image are compatible with it.
