Subject: [PATCH] Fix profiles data model attribute count parameter name and
 timestamp doc unit

ProfileData.create's parameter was named droppedAttributesCount, but the
value is exposed via getTotalAttributeCount() and ProfileMarshaler derives
the dropped count as total minus attached attributes, mirroring the Span
family. Rename the parameter to totalAttributeCount to match the getter.

SampleData.getTimestamps() javadoc said timestamps are in ms, but
SampleMarshaler serializes them to the timestamps_unix_nano field and they
must fall within the profile's nanosecond time range. Fix the unit to
nanoseconds.
