[roll] Roll cobalt-registry [prober][test_app2] Add test integer histogram metric & reports with impossible buckets

The metric & reports are added for testing `step_multiplier_float`, mainly testing whether the impossible buckets are dropped in the report.

Metric & reports added in https://fuchsia-review.git.corp.google.com/c/cobalt-registry/+/1225426 do not have any impossible bucket so they didn't serve the purpose of testing them.

For an exponential histogram with parameter:
floor: 0
num_buckets: 10
initial_step: 1
step_multiplier_float: 1.1

The buckets will be:
bucket 0 (Underflow bucket): [-inf,0)
bucket 1: [0,1)
bucket 2: [1,1.1) -> [1,2)
bucket 3: [1.1,1.21) -> [2,2) -> impossible
bucket 4: [1.21,1.33) -> [2,2) -> impossible
bucket 5: [1.33,1.46) -> [2,2) -> impossible
bucket 6: [1.46,1.61) -> [2,2) -> impossible
bucket 7: [1.61,1.77) -> [2,2) -> impossible
bucket 8: [1.77,1.95) -> [2,2) -> impossible
bucket 9: [1.95,2.14) -> [2,3)
bucket 10: [2.14,2.36) -> [3,3) -> impossible
bucket 11 (Overflow bucket): [2.36, inf) -> [3, inf)
