RFR: 8331402: G1: Remove is_active() calls in G1HRPrinter logging [v2]

[Thomas Schatzl]

> Hi all,
> 
>   the `is_active()` call for the various G1HRPrinter methods is unnecessary as the `log_trace()` call will do the exact same check again anyway.
> 
> Testing: gha, local compilation
> 
> Based on #19058.
