RFR: 8296469: Instrument VMError::report with reentrant iteration step for register and stack printing

[Axel Boldt-Christmas]

Add reentrant step logic to VMError::report with an inner loop which enable the logic to recover at every step of the iteration.

Before this change, if printing one register/stack position crashes then no more registers/stack positions will be printed.

After this change even if the VM is unstable and some registers print_location crashes the hs_err printing will recover and keep attempting to print the rest of the registers or stack values.

Enables the following
```C++
REENTRANT_STEP_IF("printing register info", _verbose && _context && _thread && Universe::is_fully_initialized())
  os::print_register_info_header(st, _context);

  REENTRANT_LOOP_START(os::print_nth_register_info_max_index())
    // decode register contents if possible
    ResourceMark rm(_thread);
    os::print_nth_register_info(st, REENTRANT_ITERATION_STEP, _context);
  REENTRANT_LOOP_END

  st->cr();


Testing: tier 1 and compiled Linux-x64/aarch64, MacOS-x64/aarch64, Windows x64 and cross-compiled Linux-x86/riscv/arm/ppc/s390x (GHA and some local)
