perf/x86/intel: Rename DMR offcore_rsp attribute to offmodule_rspgrafted
DMR introduces Offmodule Response events in place of the legacy Offcore Response events, but it still exposes the inherited offcore_rsp PMU attribute for programming the corresponding MSR data. Rename the DMR PMU attribute to offmodule_rsp so the sysfs interface matches the underlying event name and avoids user & tooling confusion.

+description:
+ Chrome OS devices have an Embedded Controller(EC) which has access to
+ Type C port state. This node is intended to allow the host to read and
+ control the Type C ports. This binding is compatible with both the
+ cros-ec-typec and cros-ec-ucsi drivers. The cros-ec-typec driver
+ supports the host command interface used by the Chrome OS EC with a
+ built-in Type-C port manager and external Type-C Port Controller
+ (TCPC). The cros-ec-ucsi driver supports the USB Type-C Connector
+ System Software (UCSI) interface used by the Chrome OS EC when the
+ platform has a separate power delivery controller (PDC). The node for
+ this device should be under a cros-ec node like google,cros-ec-spi.
