  [libc] Mark operator== const to avoid ambiguity in C++20. (#68805)

C++20 will automatically generate an operator== with reversed operand
order, which is ambiguous with the written operator== when one argument
is marked const and the other isn't.

This operator currently triggers -Wambiguous-reversed-operator at usage
site libc/test/UnitTest/PrintfMatcher.cpp:28.
