Fix non-deterministic compilation for const-string...

... in inlined methods that are not in the boot profile.
If such string is not in the boot image for other reasons,
do not resolve the string and use the kBssEntry load kind.

Boot image sizes for aosp_taimen-userdebug:
 - before:
   arm/boot*.art: 12349440
   arm/boot*.oat: 19862024
   arm64/boot*.art: 16609280
   arm64/boot*.oat: 23568592
 - after:
   arm/boot*.art: 12324864 (-24KiB)
   arm/boot*.oat: 19936612 (+73KiB)
   arm64/boot*.art: 16580608 (-28KiB)
   arm64/boot*.oat: 23642120 (+72KiB)
