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 https://github.com/wolfSSL/wolfssl/pull/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.
