RFR: 8233115: Protect ExecuteWithLog from running with redirection without a subshell [v2]

[Magnus Ihse Bursie]

> When calling ExecuteWithLog with a redirection (using > or, possibly, <), the entire command needs to be executed in a subshell, that is, inside a pair of parentheses. This is the callers obligation to ensure, but we have proven multiple times that this is hard to keep in mind, and we got several cases of race conditions due to missing this.
> 
> This PR changes the implementation of ExecuteWithLog so it checks if the command line contains redirection, and automatically add the subshell parentheses in that case. The alternative would have been to always execute in a subshell, but that would have been very expensive on Windows.
