linux-gen: timer: add poll interval time conf option
Improve timer accuracy by increasing timer pool scan rate
to twice per resolution.
Add configure file option to limit inline timer polling
rate in nanoseconds. With the default value, each thread
checks if timer pool scan is needed in maximum once per 500us.
Polling rate is increased if a timer pool is created with
a higher resolution requirement.
