Merge | SqlFileStream (Opt 1) (#2898)

* Moving SqlFileStream from netcore to common project

* WIP merge file

* Remove netfx interop classes that will be replaced with netcore interop

* Bring PathInternal methods into SqlFileStream, remove the PathInternal file.

* Simple merging

* Merge GetFullPathInternal

* Add security quality of service to common interop libraries

* I think that merges OpenSqlFileStream

* Bring in the interop for getting path names in netfx.
Seems like a lot of hassle for little benefit :/

* Most of the work to make the shared copy work with netfx

* Rewriting CreateFile to take security QoS on netfx and not on netcore

* * Fix bug in merged class
* Fix annoyance with failing unit test setup

* * SystemMemoryVersion in versions.props
* Use variable versions
* Remove output type from common project

* Remove dependency on System.Memory

* Moving code around to match standards

* Fix indenting to make next commit cleaner

* Cleanup interop files

* Cleaning up using statements and constants

* Cleanup member variables

* Make objectID back into a member variable. No need for it to be a property.

* Introduce ThrowIfDisposed

* * Remove setters for Name and TransactionContext
* Normalize the path *once*

* * Remove unnecessary fully-qualified namespace prefixes
* Fix method signatures (modifier order, argument formatting)
* Touching up comments

* Removing redundant debugs from GetFullNameInternal

* Improving GetFullPathNameNetfx

* Improving open file stream code
