[utest][core] Move timer tests from bringup to core-tests

Moves the timer tests previously found in //src/zircon/tests/timers into
the core-tests, as they exclusively test the syscall surface for timers.

This change is mostly a functional no-op, as it simply moves the
timers.cc file over into the core tests. However, there are two changes:
1. The slack check in CheckInfo was modified from an equality check to a
   greater than or equal to. In other words, we now check that a timer's
   slack is greater than or equal to the slack we set it to. We need to
   do this because the core tests are run as both a standalone binary,
   where ZX_JOB_POL_TIMER_SLACK is not set, and as individual packages
   where the slack is set to 50 microseconds (see the elf_runner for
   more info:
   https://cs.opensource.google/fuchsia/fuchsia/+/main:src/sys/lib/elf_runner/src/lib.rs;l=60).
2. The name of the test suite was changed from TimersTest to Timer to
   match other core test suites.

Having timer tests in the core-tests will help us test boot timers in
future changes.
