In the current logic for nvgpu_timeout_expired(), function always
returns 0 if fault injection is enabled. This only helps for testing
timeout not expired scenarios. However, if nvgpu_timeout_expired() is
used in a while(true) loop, it is impossible to break the infinite loop.
This patch modifies nvgpu_timeout_expired() to not expire until fault
injection counter is non-zero. The function will now return -ETIMEDOUT
when fault injection is enabled and counter is zero.

MISRA rule 17.1 forbids use of stdarg.h features defined for variable
arguments. This patch creates timers.h header for posix and QNX to
change nvgpu_timeout_expired_msg() to macro definition.

test_falcon_halt failed as nvgpu_timeout_expired returned -ETIMEDOUT when
time equal to timeout is reached and nvgpu_timeout_peek_expired returns
false when time is equal or less and true when time is greater than
timeout, leading to inconsistent return value.
Update nvgpu_timeout_expired_msg_cpu logic that is used by former.

This change switches nvgpu_timeout_peek_expired() to return a bool
instead of an int to remove advisory rule MISRA 10.5 violations.
MISRA 10.5 states that the value of an expression should not be
cast to an inappropriate essential type.

- This patch replaces "nvgpu_current_time_ms" with "nvgpu_hr_timestamp_us".
- "nvgpu_hr_timestamp_us" gives timestamp in microseconds and has better
accuracy than "nvgpu_current_time_ms" (which gives timestamp in millisecond)
