wolfBoot as library portability, Renesas fixes and TSIP AES CTR

[dgarske]

• Improvements for portability using older gcc 4.8.2.
  • Make sure wolfboot.h includes the wolfBoot_verify_* API's.
  • Remove duplicate wolfBoot_get_partition_state def.
  • Fixed issue with parsing headers when #include is # include and using "" not <> (required by customer parsing tool).
• Fix to force alignment on the flash header copy (hdr_cpy). Caused issues using wolfBoot as static library on Renesas RX.
• Fix for Renesas TSIP key types (changed in #8403).
• Fix for Renesas RX ".keystore" location in linker script.
• Fix for wolfBoot as library with Renesas to make sure crypto hardware is initialized and setup.
• Fix logic on ext_flash_check_read return code (it is supposed to return size read or decrypted).
• Fix for NO_SWAP_EXT=1 with encryption enabled.
• Added Renesas RX TSIP encrypted updates support using AES CTR. Requires Added Renesas RX TSIP AES CTR support wolfssl#8854
• Added NO_SWAP_EXT to allow support for onboard flash swap sector.
• Added WOLFSSL_NO_CT_OPS for ECDSA verify only.
• Added WC_NO_DEFAULT_DEVID to help with code size reduction.

Looks good, unsure about the removal of a prototype from image.h

Pull Request Overview

This PR enhances wolfBoot portability and reliability on Renesas platforms by addressing duplicate definitions, refining flash header parsing, and updating crypto key handling for TSIP AES CTR support.

• Removes duplicate API definitions and cleans up includes.
• Enforces proper alignment on buffers and data structures for improved flash and crypto operations.
• Updates Renesas TSIP key type mappings and enhances the initialization flow for crypto and flash subsystems.

Looks good. A bit concerned about the amount of ifdef'd code in generic files (libwolfboot.c / image.c) but I think this was needed for the correct sequence on sip_init/hal_set_key. If you think it cannot be avoided I'm fine with this.

Two places with XALIGNED_STACK attribute instead of XALIGNED
