harshal.patil 6459793edd change(security): disable Key Manager support on ESP32-C5/P4/S31

Until a revised peripheral design is available, withdraw ESP-IDF
support for it on all Key Manager capable targets.

Mahavir Jain 8abc28d71e fix(mbedtls): read crt bundle byte-wise to avoid misaligned flash access 
The offset table and the per-cert length fields of the certificate
bundle were read through uint16_t*/uint32_t* casts, which compile to
halfword/word loads at addresses with no alignment guarantee: bundles
supplied via esp_crt_bundle_set() can start anywhere, and cert entries
are byte-packed, so their 16-bit fields land at arbitrary offsets.

On chips with SOC_CPU_MISALIGNED_ACCESS_ON_PMP_MISMATCH_ISSUE (DIG-694:
ESP32-C6/H2/H21) a misaligned load from memory-mapped flash can take a
spurious "Load access fault" when it sits within two instructions of an
access to a differently-permissioned region, observed as a crash in
esp_crt_check_bundle()/CA callback during TLS handshakes with a bundle
that happened to be placed at an odd address.
