Introduces a new utility function `ZSTD_findFrameCompressedSize_internal` which is equivalent to `ZSTD_findFrameCompressSize`, but accepts an additional output parameter `bound` that computes an upper-bound for the compressed data in the frame. The new API function is named `ZSTD_decompressBound` to be consistent with `zstd_compressBound` (the inverse operation). Clients will now be able to compute an upper-bound for their compressed payloads instead of guessing a large size. Implements https://github.com/facebook/zstd/issues/1536.
