Check the supported backends in CI (#7346)

slang-test is ran with a simple test, tests/render/check-backend-support-on-ci.slang.
And the github CI,yaml will check if certain keywords are found.
This is to prevent the regression on the CI server where a set of backend was supported at some point and it stopped supporting it siliently.
