Fold the kotlin-codegen-runtime into Moshi itself.

Rename @MoshiSerializable to @JsonClass. Like @Json, I'm anticipating
a future where there are other interesting properties on this annotation.
Perhaps a future feature where Moshi is strict and only adapts types that
have a '@JsonClass' annotation.

Also rename MoshiKotlinCodeGenProcessor to JsonClassCodeGenProcessor. We
may later support other ways of generating code here; perhaps for regular
Java types.
