This commit updates the twister workflow to use the new zephyr-runner v2 CI
runner deployment.

It also updates the workflow to use the `ci-repo-cache` Docker image, which
includes the Zephyr repository cache, because the node level repository
cache is no longer available in the zephyr-runner v2.

This commit updates the twister workflow jobs that run on the zephyr-runner
v2 to print the underlying cloud service information in the logs to help
trace and debug potential runner issues.

This commit updates the twister workflow to store ccache data in the
zephyr-runner v2 node cache.

This commit updates the twister workflow to, when available, use Redis
remote storage backend for the ccache compilation cache data.

The Redis cache server is hosted in the Kubernetes cluster in which the
zephyr-runner pods run -- the Redis remote storage backend will be ignored
if the server is unavailable.

This commit adds the compiler `--specs=*` flag to the ccache ignore option
list because ccache is unable to resolve the toolchain-provided specs file
path and will consider source files to be uncacheable if it is unable to
read the specified specs file.

Note that adding `--specs=*` to the ignore option list is not a problem
because it is unlikely for the content of the toolchain libc spec file to
change without the compiler executable itself changing.

This commit updates the twister workflow such that ccache only uses remote
Redis cache storage when available.

The purpose of this to reduce the individual runner local disk IOPS
requirement; thereby, reducing the overall load on the SAN.

This commit sets the twister timeout multiplier to 2, which effectively
increases the default test timeout from 60 to 120 seconds, because the new
cost-effective Zephyr runners may take longer to execute tests and the
default timeout is not sufficient for some tests to complete.

This commit increases the default value of `ZTEST_TEST_DELAY_MS` from 3000
to 5000 milliseconds because the current value of 3000ms may not be
sufficient for the hosts with lower CPU clock frequency (e.g. new Zephyr CI
runners with cost-effective processors).

This commit relaxes the idle event statistics test precision requirement
for emulated QEMU targets because the cycle counts may be inaccurate when
the host CPU is overloaded (e.g. when running tests with twister) and a
high failure rate is observed for this test in the CI.

This commit increases the twister build job timeout from the default value
of 6 hours to 24 hours because scheduled (weekly) build runs take longer
than 6 hours to complete.
