[kiromaru]

Update SEAL port to version 3.6.1

• What does your PR fix? Updating to a new SEAL version

• Which triplets are supported/not supported? Have you updated the CI baseline?
  Tested x64-windows-static, x64-linux, x64-osx
  x64-windows/x86-windows are not supported as the library only supports static linkage in Windows.

• Does your PR follow the maintainer guide?
  Yes

@kiromaru ,The feature test on windows is successful, but there seems to be a problem with x64-linux on linux, can you take a look?

Hi JonLiu1993,
SEAL requires at least GCC 7, that is the cause of the error. Notice that the PR pipeline was able to build x64-linux without problems. I tested it locally as well.
