[MacCatalyst] Make AppleCryptoNative_SslSetEnabledCipherSuites check …

…for 32 bit & 16 bit SSLCipherSuite (#57623)

According to CipherSuites.h, SSLCipherSuite is a 16 bit value on iOS/tvOS x64 & arm64, but on MacCatalyst that is only true on arm64. x64 is defined as 32 bit.

/* 16-bit value on iOS */
typedef uint16_t SSLCipherSuite;
/* 32-bit value elsewhere */
typedef uint32_t SSLCipherSuite;

Fixes #53120
