dbus-sdr: Initial Dynamic Sensor Stack
Migrate intel-ipmi-oem dynamic sensor stack into
phosphor-host-ipmid for more general use.
The files are copied from
https://gerrit.openbmc-project.xyz/c/openbmc/intel-ipmi-oem/+/39743
https://gerrit.openbmc-project.xyz/plugins/gitiles/openbmc/intel-ipmi-oem/+/b910987a7d832e38e9342f0946aeb555a48f9cb0
Created `libdynamiccmds` to enable dynamic sensor stack.
Minor changes in the migration include:
1, Removing the use of `commandutils.hpp` in all files since it is only used
for
```
static constexpr bool debug = false;
```
It is added to `sdrutils.hpp` instead.
2, Update lastWriteAddr to size_t to match the vector.size() type
during comparison.
3, Renamed the sensorcommand unit test to sensorcommands_unitest.cpp
4, Removed unused variables.
- sensorcommands
```
constexpr uint8_t thresholdMask = 0xFF;
```
- sensorcommands_unitest
```
double yError = std::abs(y - yRoundtrip);
```
5, Removed Intel Specific Changes
- Redfish logs
- node manager/ME
- BIOS to SEL event
6, Removed externing a global variable for sensorTree.
- Replaced it with a method that returns a singleton
- auto& sensorTree = getSensorTree(); for access
7, Replaced intel_oem namespace with dynamic_sensors
8, Removed types.hpp and use `ipmid/types.hpp` directly
- Updated the types to match ipmid/types
- Added Association and std::vector<Association>> under Value.
9, Add cpp files for sdrutils and sensorutils.
10, link libipmid as it is required for getManagedObjects needed
by sensorcommands.cpp
