asim: increase range count in high_cpu_25nodes test

Previously, the CPU was not converging for the mma_only test, such that
the standard deviation of CPU was 0.13, when it should be nearly 0. This
was due to using too few ranges for the number of nodes in the cluster,
so the ranges weren't being equally distributed across stores. This
change increases the number of ranges from 50 to 500 which is sufficient
for a more even distribution. The even distribution of ranges allows the
CPU to similarly even out across the cluster stores, resulting in a new
standard deviation of 0.01. The placement_type is now
`replica_placement`, and the ranges are distributed across the first 9
nodes to make this test more realistic by keeping the CPU below 100%.

As well, the initial workload is also removed since it did not add any
value to the test scenario, and was a cause for confusion in
understanding this test setup.

Release note: none.

Fixes #156844
