[Runtime] Compatibility with dmlc::Stream API changes (#16998)
* [Runtime] Compatibility with dmlc::Stream API changes
This commit updates TVM implementations of `dmlc::Stream`. With
https://github.com/dmlc/dmlc-core/pull/686, this API now requires
the `Write` method to return the number of bytes written. This change
allows partial writes to be correctly handled.
* Update dmlc-core version
* lint fix
