Niels Lohmann d96697c285 Grow the decode arena through a function and store its position back on every return ...

slow_string() kept its write position in locals and grew the arena through
the macro NLOHMANN_VIEW_ENSURE. The macro is now the always-inline member
arena_ensure() (a lambda is not inlined at every call site by clang, which
then keeps the position in memory: +11 % instructions on escape-heavy
strings), and a guard stores the position back into m_arena_write on every
return instead of by hand on the successful one. Instruction counts are
unchanged (clang) or 1 % lower (GCC).

Also word the complexity of back() as that of at().
