Replace CFX_ScanlineCompositor::m_iTransparency with 2 structs.

The `m_iTransparency` integer is overloaded and has different meanings
in different parts of CFX_ScanlineCompositor. Replace it with an
absl::variant to better distinguish what it actually means. Then for the
2 different contexts in which it is used, replaced the int value with a
struct, so it is easier to understand what the value stands for.
