This CL does many things:
1) Adds a new API for RegisterSendSurface to specify vendor ID and whether we should block targets with the same vendor ID.
2) Refactors the sending surface callback observer lists to maps, mirroring Android.
3) Uses WrappedShareTargetDiscoveredCallback, which wraps the passed-in `ShareTargetDiscoveredCallback` and adds blocking on vendor ID (the actual point of this CL).

The `RandBytes` functions were being placed in the `crypto` namespace,
which collides with Chromium's namespace of the same name. Within,
`RandBytes` was defined with almost-the-same API. Then in Chromium
builds, the Chromium header would be used instead (though somewhat
inconsistently).
This creates a lot of pain for Chromium development as there's a
third-party repository directly depending on headers from Chromium's
source tree, and is against the third-party policies for that reason.
There are a number of other headers that mirror Chromium and are
swapped out in the Chromium build that will cause similar pain, such as:
```
include "crypto/aead.h"
include "crypto/ec_private_key.h"
include "crypto/hkdf.h"
```
This CL provides a template for how to get rid of these header swaps and
give a platform abstraction in nearby instead.
We provide a platform abstraction in `platform/crypto.h` (really in
`platform/implementation/crypto.h`) which is implemented in
`platform/implementation/shared/crypto.cc`. However that implementation
is removed by `#ifdef` when in the Chromium build.
Then, in the Chromium repo, we will add (separately) an implementation
of the same abstraction in `//third_party/nearby/platform_impl` with GN
rules to include it in the build. It will replace the implementation
from the nearby repo.

Remove CryptoSpan, use absl::Span
The header swapping of Chromium crypto libraries is
problematic, but absl::Span will convert to base::span
so there's no need for the typedef even without
removing the header swapping yet.

Adds authentication status to `ConnectionInfo`, which will pass the result of the authentication to clients when the connection is complete. See go/cros-nearby-presence-np-nc-authentication for details. This will be used in follow up CL to communicate the authentication status to clients of RequestConnectionV3().
