print-rtl: Fix printing of CONST_STRING in DEBUG_INSNs [PR93399]
The following testcase fails to assemble, as CONST_STRING in the DEBUG_INSNs
is printed as is, so if it contains \n and/or \r, we are in trouble:
.loc 1 14 3
# DEBUG haystack => [si]
# DEBUG needle => "
"
In the gimple dumps we print those (STRING_CSTs) as
# DEBUG haystack => D#1
# DEBUG needle => "\n"
so this patch uses what we use in tree printing for the CONST_STRINGs too.

PR middle-end/93399
* tree-pretty-print.h (pretty_print_string): Declare.
* tree-pretty-print.c (pretty_print_string): Remove forward
declaration, no longer static. Change nbytes parameter type
from unsigned to size_t.
* print-rtl.c (print_value) <case CONST_STRING>: Use
pretty_print_string and for shrink way too long strings.
* gcc.dg/pr93399.c: New test.
