[pdata] Rename methods dealing with slices of primitive type items (#5344)

* [pdata] Rename methods dealing with slices of primitive type items

- In preparation of migration to immutable slices for primitive type items the following methods are renamed:
  - `Value.BytesVal` func is deprecated in favor of `Value.MBytesVal`.
  - `Value.SetBytesVal` func is deprecated in favor of `Value.SetMBytesVal`.
  - `Value.UpdateBytes` func is deprecated in favor of `Value.UpdateMBytes`.
  - `Value.InsertBytes` func is deprecated in favor of `Value.InsertMBytes`.
  - `Value.UpsertBytes` func is deprecated in favor of `Value.UpsertMBytes`.
  - `<HistogramDataPoint|Buckets>.BucketCounts` funcs are deprecated in favor of
    `<HistogramDataPoint|Buckets>.MBucketCounts`.
  - `<HistogramDataPoint|Buckets>.SetBucketCounts` funcs are deprecated in favor of
    `<HistogramDataPoint|Buckets>.SetMBucketCounts`.
  - `HistogramDataPoint.ExplicitBounds` func is deprecated in favor of `HistogramDataPoint.MExplicitBounds`.
  - `HistogramDataPoint.SetExplicitBounds` func is deprecated in favor of `HistogramDataPoint.SetMExplicitBounds`.
