Merge "Resolve module bitness for target-host required modules"

# TODO(b/7456955): error if a required module doesn't exist.

# ALL_MODULES.*.REQUIRED_FROM_HOST and ALL_MODULES.*.REQUIRED_FROM_HOST_CROSS

# to 32-bit or 64-bit variant.

# Resolve the required module names to 32-bit or 64-bit variant for:

#   ALL_MODULES.<*>.REQUIRED_FROM_TARGET

#   ALL_MODULES.<*>.REQUIRED_FROM_HOST

#   ALL_MODULES.<*>.REQUIRED_FROM_HOST_CROSS

# If a module is for cross host OS, the required modules are also for that OS.

# Required modules explicitly suffixed with :32 or :64 resolve to that bitness.

# Otherwise if the requiring module is native and the required module is shared
