bionic: Introduce ElfReader::ReadPadSegmentNote()
ReadPadSegmentNote() finds the elf note of type
NT_ANDROID_TYPE_PAD_SEGMENT and checks that the desc value
is 1, to decided whether the LOAD segment mappings should
be extended (padded) to avoid gaps.
Cache the result of this operation in ElfReader and soinfo
for use in the subsequent patch which handles the extension
of the segment mappings.
Test: atest -c linker-unit-tests [Later patch]
Test: m && launch_cvd
