http: utility: Add base64encode
Add the base64encode() function to be used to encode binary data
to offload out of the BMC. Based on crow/utility.h, reworked for
readability.
Tested: Added unit test cases. Also verified data encoded with this
function was the same as the original binary when using
a decoder.
