Load ArtMethod* from .data.bimg.rel.ro entries.
Introduce a new .data.bimg.rel.ro section in oat files where
we store offsets of boot image objects from the beginning of
the boot image. At runtime we relocate these entries using
the actual boot image address to turn offsets to pointers.
Use the .data.bimg.rel.ro to prepare the boot image methods
used by HInvokeStaticOrDirect for PIC AOT app compilation.
Loading the ArtMethod* from .data.bimg.rel.ro instead of the
.bss avoids the initial call to the resolution trampoline.
Test: Additional test in 522-checker-sharpening
Test: m test-art-host-gtest
Test: testrunner.py --host --optimizing --pictest --npictest
Test: Pixel 2 XL boots.
Test: testrunner.py --target --optimizing --pictest --npictest
