Make mbedtls_ssl_read/write_version static inline

Reasons:
- If the transport type is fixed at compile-time,
  mbedtls_ssl_read_version() and mbedtls_ssl_write_version()
  are called with a compile-time determined `transport`
  parameter, so the transport-type branch in their body
  can be eliminated at compile-time.
- mbedtls_ssl_read_version() is called with addresses of
  local variables, which so far need to be put on the stack
  to be addressable. Inlining the call allows to read directly
  into the registers holding these local variables.
