Subject: [PATCH] GCC: ConsumeDurationNumber cannot be a constexpr

Declaring base::ConsumeDurationNumber as constexpr is not valid, as it
uses the BasicStringPiece::begin method, that is not constexpr.

build error in GCC:
../../base/time/time.cc: In function ‘constexpr base::Optional<base::{anonymous}::ParsedDecimal> base::{anonymous}::ConsumeDurationNumber(base::StringPiece&)’:
../../base/time/time.cc:67:63: error: call to non-‘constexpr’ function ‘const value_type* base::BasicStringPiece<STRING_TYPE>::begin() const [with STRING_TYPE = std::__cxx11::basic_string<char>; base::BasicStringPiece<STRING_TYPE>::const_iterator = const char*; base::BasicStringPiece<STRING_TYPE>::value_type = char]’
   67 |   StringPiece::const_iterator orig_start = number_string.begin();
      |                                            ~~~~~~~~~~~~~~~~~~~^~
