Add remote bitbang write buffer.
Change 7dd323b26 reduced remote bitbang performance a lot. This change
gets most of that performance back again, by reintroducing a write
buffer.
Performance numbers collected using DebugBreakpoint test from
riscv-tests/debug against a single 64-bit spike (RISC-V simulator)
instance. (Ubuntu 20.04.2, AMD Ryzen 5 3600)
Before Windows support was added: 3.09s
After Windows support was added: 12.67s
After this change: 4.69s
