[v23.3.x] Enable large alloc warnings above 128KiB by default #16844

Backport of PR #16828

We already have the reactor stall warnings on in "prod" and arguably the
large allocs are more important as they actually might result in a
crash.

Further the large alloc threshold automatically increases after each
warning so it's unlikely for this to be very spamy.

(cherry picked from commit 2be51c0)
Remove the passing of the large alloc warning threshold in DT.

We now set it to 128KiB by default in the binary so we don't want to
override it 256KiB in DT.

Note this doesn't affect the actual BadLogLines check as that has a
separate limit of 400KiB for marking log lines as hard failures.
