[receiver/hostmetrics] Disable deprecated process memory metrics

As described in https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/v0.68.0/receiver/hostmetricsreceiver#transition-to-process-memory-metric-names-aligned-with-opentelemetry-specification,
starting with v0.69.0 the new metrics are now enabled
and the old ones are disabled.

+  The metrics `process.memory.physical_usage` and `process.memory.virtual_usage` are now disabled by default and will be removed in v0.72.0.
+  As a replacement, the following metrics are now enabled by default: `process.memory.usage`, `process.memory.virtual`.
+  For details, see the [docs](https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/v0.68.0/receiver/hostmetricsreceiver#transition-to-process-memory-metric-names-aligned-with-opentelemetry-specification).
