Enable profile based boot image by default

Browse source 
Use profile based boot image instead of the compiled classes version.

Results using profile from ag/2815407
Storage savings:
Boot art+vdex+oat size: 78305556->61539326 (-17MB)

New system server profile has more methods (1.5MB -> 4MB oat) since it
has more coverage from use cases.

Ram savings (sample averages for CUJ test):
Average PSS of 3 runs (~100 samples total):
.Boot_vdex: 9359K -> 9902K
.oat_mmap: 21857K -> 13372K
.Heap: 29779K -> 29483K
.Boot_art: 15736K -> 18096K
.LinearAlloc: 9112K -> 8965K
Total PSS: 85846K -> 79819K (-6MB)

Average pages read from flash (512MB device) for CUJ tests (3 samples):
1508MB -> 1183MB

Bug: 37966211
Test: make and flash
