Rename mbedtls_a64_crypto_sha256_check_support() to mbedtls_a64_crypto_sha256_determine_support()

Browse source 
The Mbed TLS coding standard specifies that "check" functions must return 0
for success (i.e. feature present), while "has" functions should return 1 for
true. Since we were using "check" to do the actual check, and "has" to get the
cached value, having inverted values here would be confusing.  Therefore,
rename "check" to "determine", as that's what those functions are doing.
