base: Reinforce some symbol names

This commit renames some symbol names for base APIs to reinforce API
naming convention defined here [1]. The list of change includes:

1. `encode_base_multipart_receive_req()` to
    `encode_pldm_base_multipart_receive_req()`
2. `decode_base_multipart_receive_resp()` to
     `decode_pldm_base_multipart_receive_resp()`
3. `struct pldm_multipart_receive_resp` to
     `struct pldm_base_multipart_receive_resp`
4. `struct pldm_multipart_receive_req` to
     `struct pldm_base_multipart_receive_req`

This also removes `__attribute__((packed))` from
`struct pldm_base_multipart_receive_req` to adapt [1].
