Vyacheslav Egorov 692952dfd0 Pass operator_new_alignment value through gn script into GN args. (flutter/engine#7031)
Background:

Some allocators (tcmalloc) don't provide alignment guarantees that
match clang's default expectations, which causes crashes when using
clang compiled binary with such allocators.

For example clang can produce movaps instructions to initialize newly
allocated object - which would crash if result of ::operator new() is
not 16 bytes aligned.
