Add System.Management (dotnet/corefx#24719)

* First pass building

* Remove Instrumentation and WMIGenerator

* Resources to as used on CoreFX

Opportunistic: some small changes related to warnings

* Removed hard coded path to load wminet_utils

Also moved so DllImport to use Common version of files.

* Added ref, sln, and single basic test

Code builds and pass single test

* Add CoreFX source header

* Removing unused using directives

* clean src proj references

* A bit more test coverage (19%)

* Sanitizer pass with default settings

* Adding WMIGenerator

This allows methods to generate CodeDom for strong type access to WMI
objects.

* Missing files from previous commit

* Some extra clean-up missed by SSS

* Removing #ifdef dead code

* Add pkg project

* Removing more dead code

* Removing dead code and small improvement to tests

* Suppress CA1821 when generating PNSE assembly

cases disable CA1821.

* Source changes from CR (so far)

* Targets and package issues

* Go back to project targets and settings

Per conversation w/ @weshaggard it should follow the same model as
System.DirectoryServices not the packages of dlls that do not exist on
desktop. This still is not expected to be fully correct but it puts the
projects closer to the targets that they will have in the end.

* Description for the System.Management package.

* Match supported pkg frameworks

* Skip tests on Windows Nano

* Missed files from previous commit

* Generate PNS Assembly for uap

* Add references needed by uap for PNS assembly

* PNS assembly message

* Fixing package issue

Make Expect: 100-continue handling more robust (dotnet/corefx#24789)

When libcurl sends an Expect: 100-continue header, if it gets back a success error code, it may avoid sending the remaining payload and also may keep the connection open, which can confuse servers that expect to receive the fully promised payload and that don't close the connection when sending a final success status code instead of 100 continue.  To mitigate this, we simply change the default ExpectContinue == null behavior to be the equivalent of ExpectContinue == false rather than to be "do whatever the platform decides".  This also more closely aligns with WinHttpHandler and ManagedHandler, where effectively the "platform" in those cases decides that the default is disabled.

For ManagedHandler, currently we're mimicking behavior like that libcurl employed and may sometimes not send the full payload but still keep the connection open.  Instead, make sure we either always send the full payload or close the connection.

Add Span/Memory overrides to StreamWriter (dotnet/corefx#24725)

- Refactors StreamWriter to work in terms of Span/Memory.
- Adds TextWriter-overrides for the Span/Memory-based methods.
- Exposes the new members from the ref.
- Adds tests for the new methods.
- Respond to API review feedback that we should be naming parameters to match existing overloads, here using `buffer` instead of `source` or `destination`, since `buffer` is already used in overloads on these types.
