Remove capture_warnings.sh and print_warnings.cmake

This is a separate feature, unrelated to system versioning

We may keep it or not, but either way, it's a separate discussion,
if we keep it, it won't be in the system versioning branch

BUILD/capture_warnings.sh

-#!/bin/bash
-warn_path=$1
-warn_mode=$2 # 'late', 'early' or 'both'
-shift 2

-warn_file="$warn_path/compile.warnings"
-suppress_file="$warn_path/suppress.warnings"
-
-# suppress_warnings:
-#
-# 1. treat STDIN as sequence of warnings (w) delimited by ^~~~... lines
-#
-# 2. sanitize each w to matchable m:
-#    a. ignore 'In file included from' lines;
-#    b. protect BRE chars;
-#    c. ignore text coords (NNN:NNN);
-#    d. convert multiline to X-delimited single line.
-#
-# 3. match sanitized m against X-delimited suppress.warnings:
-#    if match not found print w to STDOUT.
