toast_internals.h described the header of a compressed-in-line varlena a second time, as toast_compress_header, with its own TOAST_COMPRESS_* macros to read and write the tcinfo word. varatt.h already describes the same bytes as varattrib_4b.va_compressed and provides equivalent macros that act as setter and getter of this information, as of VARDATA_COMPRESSED_GET_EXTSIZE() and GET_COMPRESS_METHOD(). Let's remove the duplicate definition, and switch the TOAST code to use the macros from varatt.h. There should be no behavior change. Note that toast_compression.h is removed from toast_internals.h, added to the C files where its declarations are required.
