Update PeerConnectionDependencyFactory to use CryptoOptions::Srtp.

This change updates Chromium to use CryptoOptions::Srtp fields to configure the
command line switches for WebRTC crypto instead of the old deprecated fields.

This API was changed in: https://webrtc-review.googlesource.com/c/src/+/105180

Once this change lands the top level fields:
  absl::optional<bool> enable_gcm_crypto_suites and
  absl::optional<bool> enable_encrypted_rtp_header_extensions

Will be removed and their replacements will be under the Srtp sub struct.
