Subject: [PATCH 08/11] OvmfPkg: Add CsvDxe driver
CsvDxe creates and installs the CsvSharedMemory protocol.
CSV VM needs the shared memory to exchange data with external devices.
To improve the performance, CsvSharedMemory protocol pre-allocates
huge shared memory chunk as a pool.
When reqeusted, it allocates small pieces of shared memory from the
pool and records the allocated memory in a list.
When finished, the shared memory pieces are returned to the pool and
removed from the record list.
