Description: Add an option to use the input model bytes (ORT format only) directly without copy at session creation

Motivation and Context

• When we load an ORT format model from given byte array, we copy the array first to ensure the bytes are valid. There is a recent issue Prevent data copy in CreateSessionFromArray  #8328, where the current behavior may cause extra memory usage where iOS may kill the process
• Add an option to not copy the input model bytes, however, in this case, the user will have to guarantee the buffer is valid until the session is created (this is the 1st step to reduce memory consumption). The default behavior is still copying the model bytes. The user has to specifically set the option to disable the copy.
• Added UT cases

if removing the "end" comment, can you also remove the "begin" one and change the note to say "The NNAPI EP options..." instead?
