Paths default to SyntaxHostNative because that makes the semantics post-patch equivalent to pre-patch.  Normalized form is basically unix form, so if the syntax ends up as ePathSyntaxPosix (either because it was explicitly specified or because host was specified and your host is posix), then normalization and de-normalization are both no-ops.  

SmallString<64> just means that it keeps 64 bytes on the stack, and if it grows longer than that, it will fallback to help allocation.  It still supports arbitrarily long strings, but paths tend to be small, so that's why a small number was chosen.
