Suppress repeating warnings/errors from repeating in swift build output when building swift package

[valeriyvan]

Description

swift build output polluted with repeating same warning multiple times.

Expected behavior

Repeating warnings should be suppressed to improve output readability.

Actual behavior

Here's real life example where the same warning repeats 8 times:
