Exclude SFrameDecrypterStream & SFrameEncrypterStream from Interop 2025

[nt1m]

Test List

web-platform-tests/wpt#55520
web-platform-tests/wpt-metadata#8123

Rationale

This was added 2 days ago by web-platform-tests/wpt@650d061 and CODEOWNERS didn't block that change.

These are very recent spec changes: w3c/webrtc-encoded-transform@7cde254 that would be good to stabilize before including in Interop.

@guidou has already approved the WPT PR, so this works for Chrome.
