AK+IPCCompiler: Get rid of BufferStream overloads for size_t

Since BufferStream is about creating specific binary stream formats,
let's not have a flaky type like size_t in there. Instead, clients of
BufferStream can cast their size_t to the binary size they want to use.

Account for this in IPCCompiler by making String lengths always 32-bit.
