Improve buffer size distribution in fuzz tests
[ Merge of http://go/wvgerrit/160957 ]
When a buffer size is fuzzed, use the modulo operation, instead of
std::min, to create an even distribution.

Split fuzzed data into separate buffers so AddressSanitizer can detect
all out-of-bounds accesses.

[ Merge of http://go/wvgerrit/147110 ]
The OEMCrypto_DestBufferDesc had fields address/address_length renamed
to clear_buffer/clear_buffer_length in v17. However this was not updated
for the fuzz tests thus causing some code coverage errors. This should
fix those errors.
