[ComputePressure] Make ComputePressure as a service.
The patch makes ComputePressure as a service and the major
changes are:
1. Move ComputePressureManager and related classes from
content/browser to services/device. Rename ComputePressureManager
to ComputePressureManagerImpl.
2. Rename ComputePressureHost to ComputePressureServiceImpl.
3. ComputePressureSample data are collected in service now and then
send to ComputePressureServiceImpl. If the data changes and meets
frequency requirement, ComputePressureServiceImpl will send the
data to Blink.
4. CpuProbe collects data only when there is active
ComputePressureObserver. It stops collecting when all
ComputePressureObservers become inactive.
The compute_pressure_different_quantizations_across_iframes test
fails in this patch. However, there is no concept of the quantization
in the newest spec any more and we will remove this test in the
future.
