BZ:https://bugzilla.tianocore.org/show_bug.cgi?id=3013

In order to leverage HTTP IO related functions implemented in HttpBootDxe
for edk2 Redfish REST EX HTTP driver instance, we would like to pull out
HTTP IO related functions from HttpBootDxe to a helper library under
network package.

This set of patches is for the new library HttpIoLib. We can help to
revise HttpBootDxe to use HttpIoLib, however we will need the owner
of HttpBootDxe to verify the functionality of HTTP boot becuase I don't
have the environment for that.

Note: This set of patch can't pass CI/ECC check becasue the specific
format of copyright information is not supported yet on files other than
.c and .h.

Add HTTP IO helper library which could be sued by HTTP applications
such as HTTP Boot, Redfish HTTP REST EX driver instance and etc.
