include/linux/lz4.h: add some missing macros
Currently, LZ4_DISTANCE_MAX and LZ4_DECOMPRESS_INPLACE_MARGIN are
defined in the erofs subsystem for LZ4 in-place decompression, which is
somewhat unsuitable since they should belong to the LZ4 itself and
may change with future LZ4 codebase updates.
Move them to include/linux/lz4.h to match the upstream LZ4 library [1].
No logic changes.
