Use std::string for get_device_*_string helpers (#737)

Browse Source 
* Use std::string for get_device_*_string helpers

Removes need to use BufferOwningPtr to avoid memory leaks.

* Rename get_device_info to get_device_info_string

Makes it more obvious that it should only be called for device queries
that return strings.

* Tokenize extensions in is_extension_available

Avoids the potential issue where one extension name is a prefix of
another.

* Throw exception when device info size is 0
