Move to embedded base64
Base64 encode/decode is a relatively simple algorithm, and currently
libcper takes a dependency on libb64 for this. libb64 does not have
methods for determining the encoded size or decoded size, and rely on
the user to provide the right buffer sizes, which libcper currently
approximates as 2X the input size (which is incorrect).
This commit removes the libb64 dependency entirely, and inlines a
libcper specific base64 encoder and decoder, using EDK2-allowed types.
The implementation itself is unique to libcper and makes the following
design decisions.
1. Malloc is performed within the base64_<> functions. This reduces the
number of malloc calls total, and removes the need for separately
determining the output size.
2. Arguments are passed in by EDK2-types under the assumption that this
will keep compatibility with EDK2 implementations.
3. Incremental parsing is not supported. CPER records are expected to
be algorithmically small, and buffered such that the entire value
fits in memory. This was already an assumption, but dropping the
support for incremental encoding significantly reduces the amount of
code to support it. It could be added back in the future if needed.
