Performance logs should contain the entire query string

[chipkent]

Query logs contain shortened versions of query strings. This makes it very difficult to determine which lines are causing problems.

This is possibly related to #4918 .

Consider this example.

import deephaven.perfmon as pm

upl = pm.update_performance_log()
qopl = pm.query_operation_performance_log()
qpl = pm.query_performance_log()
pml = pm.process_metrics_log()
pil = pm.process_info_log()
ssl = pm.server_state_log()

from deephaven import empty_table, time_table

def fast(x:int) -> int:
    return int(x*(x+1)/2)

def slow(x:int) -> int:
    val = 0
    for i in range(x):
        val += i+1
    return val

from timeit import timeit
print(timeit(lambda : fast(100)))
print(timeit(lambda : slow(100)))

# Static table and query startup performance go to qopl table
t = empty_table(100).update_view(["A = ii"])
t2 = t.update(["X = fast(A)"])
t3 = t2.update(["Y = slow(A)"])

The updates are all showing up without formulas.

This is completely unrelated to #4918, and has been the "state of the art" since 2016 or earlier.
