This pull request introduces some base datatypes and functionality
required for **Peras**, along with supporting tests, benchmarks, and
documentation.

Specifically, it adds:

* `PerasWeight` and `PerasCert`, which associate a weight with a block.
* `PerasWeightSnapshot`, a type for capturing the known weight state of
blocks
* Functions for computing weights of chains and fragments.
* Tests, microbenchmarks, documentation, and runnable examples for
weight-related utilities.

---

### **Peras types and weight computation**

* Added module `Ouroboros.Consensus.Block.SupportsPeras`, defining types
and logic for Peras weights and certificates.
  * Key elements are re-exported via `Ouroboros.Consensus.Block`.
* Added module `Ouroboros.Consensus.Peras.Weight`, introducing
`PerasWeightSnapshot` and weight computation functions for chains and
fragments.

---

### **Documentation**

* Added glossary entries for **Peras**, **weight boost**, and **chain
fragment weight** in `glossary.md`.
* Created a new benchmarks page explaining how to run Peras-related
microbenchmarks and their purpose.

---

### **Tests and benchmarks**

* Introduced benchmark suite `PerasCertDB-bench`, including a weight
computation microbenchmark (`bench/PerasCertDB-bench/Main.hs`).
* Added module `Test.Consensus.Peras.WeightSnapshot` with property-based
tests for weight computation on chains and fragments.

---

### **Regression**

The new code added with this PR is not actually used, so it shouldn't
introduce regressions.
