fix confusing status messages during resume

Recently, (after b503fdef02f) OpenOCD started to notify user about hart
state updates. This causes confusion in some cases since some internal
updates to the hart state should not be visible to the user as these are
implementation details. For example situation like this:

```
> reset halt
JTAG tap: riscv.tap tap/device found: 0xdeadbeef ...
> resume
[riscv.cpu0] Found 4 triggers
riscv.cpu0 halted due to single-step.
[riscv.cpu1] Found 4 triggers
riscv.cpu1 halted due to single-step.
[riscv.cpu2] Found 4 triggers
riscv.cpu2 halted due to single-step.
[riscv.cpu3] Found 4 triggers
riscv.cpu3 halted due to single-step.
```
likely confuse people.

There is no issue with the resume functionality. It`s just that
resume internally causes single-step that causes hart state
to change.

This commit disable calling of user-specified (and default)
callbacks during the "hidden" step operation disabling these
confusing messages
