Refactor linker files from compiler/ to dex2oat/.

This shifts some code from the libart-compiler.so to dex2oat
and reduces memory needed for JIT. We also avoid loading the
libart-dexlayout.so for JIT but the memory savings are
minimal (one shared clean page, two shared dirty pages and
some per-app kernel mmap data) as the code has never been
needed in memory by JIT.

aosp_angler-userdebug file sizes (stripped):
  lib64/libart-compiler.so: 2989112 -> 2671888 (-310KiB)
  lib/libart-compiler.so: 2160816 -> 1939276 (-216KiB)
  bin/dex2oat: 141868 -> 368808 (+222KiB)
LOAD/executable elf mapping sizes:
  lib64/libart-compiler.so: 2866308 -> 2555500 (-304KiB)
  lib/libart-compiler.so: 2050960 -> 1834836 (-211KiB)
  bin/dex2oat: 129316 -> 345916 (+212KiB)
