Seen with mbedTLS 4.0.0. mbedTLS 4.0.0 renamed `mbedcrypto` lib to `tfpsacrypto`, while also keeping a copy under the old name to aid transition. However, this compatibility logic is broken for MSVC static builds, and the old name missing. Work around by looking for the new name in the raw detection codepath. Note that using `pkg-config`-based detection also works as a workaround.
