NetworkPkg: Update HttpDxe driver to consume EFI_HTTP_UTILITIES_PROTOCOL

NetworkPkg: Update HttpDxe driver to consume EFI_HTTP_UTILITIES_PROTOCOL

v2:
* Register a notification function to be executed for Http utilities protocol
in the drivers entry points.

Since we add EFI_HTTP_UTILITIES_PROTOCOL support, HttpDxe driver should
be updated to remove internal http utilities functions and consume this
protocol directly.
