feat: parallel gtest

[IlyasRidhuan]

Gtests take a relatively long time to run, and avm_tests will start to take longer with the introduction of more lookups.

This uses the gtest-parallel script to run the bb tests in parallel.

In some tests we get a 50% improvement in test times, while others remain mostly the same (it's mostly down to the structure of the test binary)

Benchmark results

Metrics with a significant change:

• tx_sequencer_processing_time_ms (0): 13.6 (+31%)
• note_successful_decrypting_time_in_ms (8): 176 (-34%)

Detailed results

All benchmarks are run on txs on the Benchmarking contract on the repository. Each tx consists of a batch call to create_note and increment_balance, which guarantees that each tx has a private call, a nested private call, a public call, and a nested public call, as well as an emitted private note, an unencrypted log, and public storage read and write.

This benchmark source data is available in JSON format on S3 here.

Values are compared against data from master at commit 5c5b6270 and shown if the difference exceeds 1%.
