[exporter/prometheusexporter] Support for custom bucket native histograms

[MoreraAlejandro]

Component(s)

Prometheus exporter

Is your feature request related to a problem? Please describe.

Follow-up for #43053.

As per prometheus documentation:

-53 is a schema for so-called custom bucket boundaries or short custom buckets, while the other schema numbers represent the different standard exponential schemas (short: standard schemas).

We decided in #43053 that this will be implemented in a separate PR, so this is the issue for that

Describe the solution you'd like

When the schema is set to -53 we need to do what is described in this documentation page.
