test: improve test coverage for xxxx_genesis_sanity_check tests

[hansieodendaal]

Description

Improved test coverage for genesis block sanity checks when run locally in debug or release mode. This PR removed the need for fn XXXX_genesis_sanity_check() tests to be compiled for a specific target network, and for the global static network variable to be set for a target network, i.e. let _ = Network::set_current(Network::Esmeralda);.

cargo.exe test --release --lib blocks::genesis_block will now run all 6x tests serially .

This also works in a CI environment where cargo nextest is called, without any impact on overall runtime performance.

Motivation and Context

All 6x fn XXXX_genesis_sanity_check() tests could not be run with a single target network build.

How Has This Been Tested?

Locally and on CI.

What process can a PR reviewer use to test or verify this change?

• Review code changes
• Review CI unit test output where all 6x tests in question should be executed in a single test run:
