testenv: abstract run-with-timeout into testenv

Browse source 
This lifts the logic to run a subcommand with a timeout in a test from
the runtime's runTestProg into testenv. The implementation is
unchanged in this CL. We'll improve it in a future CL.

Currently, tests that run subcommands usually just timeout with no
useful output if the subcommand runs for too long. This is a step
toward improving this.

For #37405.
