E32 direct network layer routing in coprocessor (w/ recent messages buffer)

[SukuWc]

Refactor in grid_common

• [x] remove led alert from connect and disconnect logics
• [x] separate recent_messages_buffer from grid_msg_model
• [x] check if partner hwcfg is ever used?
• [x] check if partner local_token and partner_token is ever used?
• [x] separate volatile double_buffers from grid_port_model
• [x] separate buffers from grid_port_model

Integrate into grid_pico

• 4x struct grid_port_model for partner status and partner phi

• grid_msg_state for recent messages buffer

• receive direct

  • [x] set partner phi
  • [x] set partner status (optional)
  • [x] calculate partner timeout (optional)

• receive broadcast

  • [x] grid_msg_recent_fingerprint_find
  • [x] grid_msg_string_transform_brc_params
  • [x] create 3 copies to tx buckets

• [x] grid_port_timeout_try_disconect

• [x] updated broadcast receive buckets are still sent through via SPI

• [x] direct receive buckets are still sent through via SPI

Integrate into grid_esp

• receive direct
  • [x] store partner hwcfg and status
• receive broadcast
  • [x] copy from doublebuffer to rx buffer without change because grid_msg_string_transform_brc_params is already done
