[Health] add delete by client id and fetch unit support

[connor-callaghan]

This pull request focuses on unit conversions, and record deletion capabilities. The changes improve the flexibility of data handling and add support for more granular operations on health records.

Unit Conversion:

• HealthDataConverter: Added support for unit conversions in WeightRecord, HeightRecord, BodyTemperatureRecord, and BloodGlucoseRecord by introducing a dataUnit parameter to the convertRecord method. This allows dynamic conversion based on specified units (e.g., kilograms to pounds, Celsius to Fahrenheit).

Metadata:

• HealthDataWriter: Updated various methods (writeData, writeWorkoutData, writeBloodPressure, and writeMeal) to include optional clientRecordId and clientRecordVersion parameters in the Metadata object. This facilitates better tracking and versioning of health records. [1] [2] [3]

Record Deletion:

• HealthDataOperations: Introduced a new deleteByClientRecordId method to allow precise deletion of health records using clientRecordId and dataTypeKey. This provides a more targeted approach to record management.

Data Retrieval:

• HealthDataReader: Added support for specifying a dataUnit parameter during data retrieval, enabling unit-specific filtering and processing in the getData method. [1] [2]
