Rename Pools class to PoolFactory (resolves class/namespace name clash)

The static pool factory `Pools` lived inside the `LiveKit.Internal.FFI.Pools`
namespace, so once FFIClient moved into LiveKit.Internal.FFI the namespace
shadowed the class and forced a `FfiResponsePools` alias at the call site.

Rename the class to `PoolFactory` (also a clearer name than `Pools.Pools`),
rename the file to match, and drop the now-unneeded alias in FFIClient.cs.
Internal-only type with a single call site; no API impact.

Verified by compiling the LiveKit assembly via csc.
