Subject: fix: suppress clang -Wimplicit-const-int-float-conversion in
 v8_binding_for_core

fixes the following error on build:

../../third_party/blink/renderer/bindings/core/v8/v8_binding_for_core.h:272:38: error: implicit conversion from 'const uint64_t' (aka 'const unsigned long') to 'double' changes value from 18446744073709551615 to 18446744073709551616 [-Werror,-Wimplicit-const-int-float-conversion]
  272 |   double fmod_value = fmod(trunc(d), kMaxULL + 1.0);
      |                                      ^~~~~~~ ~

This error appears to be caused by https://chromium-review.googlesource.com/c/chromium/src/+/5224201
but doesn't appear to be reproducible in chrome.

Given the nature of this code it appears safe to ignore this check.
