Subject: [PATCH] fix(mbedtls): link esp-cryptoauthlib to mbedcrypto library

If the certificate bundle feature is disabled then the mbedtls
component library becomes interface only component and hence
adding esp-cryptoauthlib as its PRIVATE dependency does not work.

Instead the esp-cryptoauthlib should be added as PRIVATE dependency
for mbedcrypto library (for alternate ECDSA implementation).
