Use global constant instead of member for HPACK and QPACK entry size overhead.

Constexpr instead of const allows for the compiler to inline the value.
However, Chromium does not support constexpr members, so this variable needs to
be moved out of the class.  (Chromium does not support inline constexpr either.)
See go/totw/140.
