/**
* Exercises ChromeUtils.getWMFContentDecryptionModuleInformation(), which
* dispatches through UtilityMediaServiceChild::GetKeySystemCapabilities and
* populates dom::CDMInformation entries.
*
* MFCDMParent::GetAllKeySystemsCapabilities enumerates a compile-time-fixed
* table of key systems, each tagged SecureLevel::Software or
* SecureLevel::Hardware. That tag becomes capabilities.isHardwareDecryption()
* over IPDL. This test mirrors that table and asserts every reported CDM's
* isHardwareDecryption matches its static tag, so the assertion holds across
* hosts that expose different subsets of key systems (CI without hardware
* DRM, developer hosts with hardware-backed PlayReady, hardware-only
* configurations).
