Harvest the netstandard2.0 refs for the crypto libraries

The crypto libaries currently have a frozen API surface for
netstandard2.0 because they are either inbox or harvesting
older platforms that support that API surface. Given that we
should simply harvest the NS references to avoid them from adding
apis they don't support everywhere.

System.Security.Cryptography.Xml depends on System.Security.Cryptography.Pkcs
for netstandard build so we need to restore it to the targeting pack.

Convert [DSA/RSA/Ecc]SecurityTransforms and X509SignatureGenerators to new ASN.1 APIs

This changes a lot of types designed for AsnSerializer to use the AsnXml code generator, and moves a number of those types from S.S.C.Algorithms to Common because the SecurityTransforms types are dual-compiled.

The workflow is similar to:

* Change all of the SecurityTransforms types to use the new types added during the key import/export feature.
* Change those types to use AsnXml generated code instead of AsnSerializer
* Move the types to Common source to fix S.S.C.X509Certificates build breaks
* Now that the types are already included in S.S.C.X509Certificates, make X509SignatureGenerator types use them, too.

Add hybrid support for OpenSSL 1.0 and 1.1

This changes the functional code to use OpenSSL 1.1 API in the places where the API changed. "apibridge" provides equivalent methods for the OpenSSL 1.0 environment.

The following configurations have been tested:

* Non-portable against OpenSSL 1.0
* Non-portable against OpenSSL 1.1
* Portable, built against OpenSSL 1.0 and run against OpenSSL 1.0
* Portable, built against OpenSSL 1.0 and run against OpenSSL 1.1
* Portable, built against OpenSSL 1.1 and run against OpenSSL 1.0
* Portable, built against OpenSSL 1.1 and run against OpenSSL 1.1

In opensslshim, the PER_FUNCTION_BLOCK macro style has been broken up into a named purposes:

* REQUIRED_FUNCTION(fn)
  * API that we use unconditionally, regardless of version
  * Formerly PER_FUNCTION_BLOCK(fn, true)
* NEW_REQUIRED_FUNCTION(fn)
  * API that we use unconditionally in paths that only exist against OpenSSL 1.1, is not probed for when the runtime is 1.0
* LIGHTUP_FUNCTION(fn)
  * API that might not exist, must be probed with API_EXISTS checks before being utilized
  * Formerly PER_FUNCTION_BLOCK(fn, false)
* FALLBACK_FUNCTION(fn)
  * API that is required on OpenSSL 1.1, and when not found will bind to a method named local_#fn in the shim library
* RENAMED_FUNCTION(fn,oldfn)
  * Handles a rename with no signature change from oldfn to newfn, binds appropriately based on the runtime library.
* LEGACY_FUNCTION(fn)
  * API that we use unconditionally in paths that only exist against OpenSSL 1.0, is not probed for when the runtime is 1.1.

Two new #defines are available, but ideally need no further usage:

* NEED_OPENSSL_1_0
  * Defined when building portable, or on non-portable when the headers are OpenSSL 1.0
* NEED_OPENSSL_1_1
  * Defined when building portable, or on non-portable when the headers are OpenSSL 1.1

Fix build break caused by conflicting changes

Ifdef use of Reflection.Emit for netstandard build of System.Runtime.InteropServices tests. I choose to ifdef it out instead of
refactoring into small files since this change is temporary. These ifdefs should be removed once Reflection.Emit is added to netstandard2.1.

Erase temporary copies of plaintext during de/padding operations

When symmetric block padding is added, or removed, the
UniversalCryptoDecryptor and UniversalCryptoEncryptor classes make a
temporary buffer to hold the padded result (for encryption this is the input to
the cryptographic transform, for decryption it is the output before calling
DepadBlock).

While these buffers are usually marked as unused by the GC in short order, and
overwritten by new objects in short order, some applications are more sensitive
to having plaintext residuals in memory; and we should clear these out before
abandoning them to the garbage collector.

Ensure that TrySetECDHNamedCurve is always called, enabling ECDHE ciphersuites

Moves the call to TrySetECDHNamedCurve above the early abort when the server default protocols are selected.

This ensures that when SslStream is used as a TLS server that the ECDHE ciphersuites are available for "Perfect Forward Secrecy".

By using an SslStream-based TLS server and the openssl s_client utility as a client, verified that the ciphersuite went from ECDH-ECDSA-AES256-GCM-SHA384 to ECDHE-ECDSA-AES256-GCM-SHA384 (and AES256-GCM-SHA384 to ECDHE-RSA-AES256-GCM-SHA384 for RSA).

Add unloadable AssemblyLoadContext API and tests (dotnet/corefx#32002)

* Add unloadable AssemblyLoadContext API and tests

The change is based on dotnet/corefx#14763, but I had to change many things due to
the fact that the project.json files are not used anymore and due to the
slighly different semantics of the Unloading event, which now fires when
the unloading is about to start and doesn't indicate the unload is
almost done as before.

Additional changes:
* Tests for all remaining unsupported features:
  * delegate marshalling for types in collectible assemblies
  * FixedAddressValueTypeAttribute
  * COM interop
* Removed checked in binary System.Runtime.Loader.Test.Assembly.dll,
modified the msbuild projects to build it at the build time instead.
* Added the new APIs to ApiCompatBaseline

Remove package for System.IO.Pipes.AccessControl

We no longer need to ship an updated version of this package
so remove it as well as all but the netcoreapp and uap build
configurations. The API surface is frozen because it is inbox on
uap so we cannot do anything beyond service the package which can
happen in the servicing branches. If we need to make a larger change
to this library we can always bring back the package and harvest
all the older assets.
