[Profiler] Contention profiling: add blocking thread name

[gleocadie]

Summary of changes

Add the blocking thread name as tag on sample.

Reason for change

In a previous PR, we provide the blocking thread id only. The backend would need the name to display something useful.

Implementation details

Add and propagate the blocking thread name.

Test coverage

Update the current test.

Execution-Time Benchmarks Report :stopwatch:

Execution-time results for samples comparing the following branches/commits:

• This PR (5981)
• master

Execution-time benchmarks measure the whole time it takes to execute a program. And are intended to measure the one-off costs. Cases where the execution time results for the PR are worse than latest master results are shown in red. The following thresholds were used for comparing the execution times:

• Welch test with statistical test for significance of 5%
• Only results indicating a difference greater than 5% and 5 ms are considered.

Note that these results are based on a single point-in-time result for each branch. For full results, see the dashboard.

Graphs show the p99 interval based on the mean and StdDev of the test run, as well as the mean value of the run (shown as a diamond below the graph).
