Rewrite Class init entrypoint to take a Class arg.

Fixes invalid type index being passed to the entrypoint for
class init check across dex files when the target type does
not have a TypeId in the compilation unit's DexFile.

The size of the aosp_taimen-userdebug prebuilts:
  - before:
    arm/boot*.oat: 16782748
    arm64/boot*.oat: 19764400
    oat/arm64/services.odex: 20162432
  - after:
    arm/boot*.oat: 16811692 (+28.3KiB, +0.17%)
    arm64/boot*.oat: 19801032 (+35.8KiB, +0.19%)
    oat/arm64/services.odex: 20232208 (+68.1KiB, +0.35%)
This increase comes from doing two runtime calls instead of
one for HLoadClass/kBssEntry that MustGenerateClinitCheck().
