Update HWCPipe

[JoseEmilio-ARM]

Description

Update the HWCPipe submodule to use the latest 2.0 release. This adds support for many more GPU counters over a wider range of Arm devices. It cannot be build for desktop, so added some flags so that the HWCPipe provider is only built for Android.

Note that HWCPipe 2.0 removed support for CPU counters. These were only used in two of our samples though, and added a note in their tutorials. Open to suggestions for a better CPU counter stats provider. For instance, we could adapt the older build of HWCPipe 1.0 to only provide CPU counters.
