The zstd decompression code, as it is right now, will most likely fail
on 32-bit systems, as the default output buffer size causes the buffer's
end address to overflow.
Address this issue by setting a sane default to the default output size,
with a value that won't overflow the buffer's end address.

- Add unzstd() and the zstd decompress interface.
- Add zstd support to decompress_method().
The decompress_method() and unzstd() functions are used to decompress
the initramfs and the initrd. The __decompress() function is used in
the preboot environment to decompress a zstd compressed kernel.
The zstd decompression function allows the input and output buffers to
overlap because that is used by x86 kernel decompression.
