Non-trivial static variables may require an initialisation routine which is invoked on first call. This happens in the `hwTimerCallback` routine when the `ElapseTimer` constructor is called, but that is unsafe to do from interrupt context. Moving this to a global variable fixes the issue. The exception may vary, but I'm getting: ``` assert failed: xQueueSemaphoreTake queue.c:1718 (!( ( xTaskGetSchedulerState() == ( ( BaseType_t ) 0 ) ) && ( xTicksToWait != 0 ) )) ```

Task queue gets hammered so needs additional consideration for esp32.
There's also an issue with having a
static ElapseTimerinside an interrupt service routine because the constructor gets called on first use from ISR, which is problematic and leads to unpredictable crashing-type behaviour.Closes #2971
