Various BasicFile improvements

* BasicFile::Open clears error_code on entry, and exits early on failure to avoid initialization of m_FileHandle
* Made BasicFile::Read handle large reads
* Made BasicFile::Write handle large writes
* Added BasicFile::WriteAll which may be optimized in the future to handle what is essentially a file copy more efficiently
