Reduce default inline storage in absl::FixedArray from 256 to 48 bytes.

With a stateless allocator and without AddressSanitizer redzones, 48 bytes of inline element storage plus the size and data pointer keep a default absl::FixedArray within one 64-byte cache line for every element type. Element types larger than 48 bytes select zero inline elements and occupy 16 bytes. A 256-byte default inline buffer wastes memory inside heap-allocated objects when member arrays hold only a few elements or allocate out of line anyway.
