[doc] Remove Limitation that Compressed Block is Smaller than Uncompressed Content
...
This changes the size limit on compressed blocks to match those of the other
block types: they may not be larger than the `Block_Maximum_Decompressed_Size`,
which is the smaller of the `Window_Size` and 128 KB, removing the additional
restriction that had been placed on `Compressed_Block`s, that they be smaller
than the decompressed content they represent.
Several things motivate removing this restriction. On the one hand, this
restriction is not useful for decoders: the decoder must nonetheless be
prepared to accept compressed blocks that are the full
`Block_Maximum_Decompressed_Size`. And on the other, this bound is actually
artificially limiting. If block representations were entirely independent,
a compressed representation of a block that is larger than the contents of the
block would be ipso facto useless, and it would be strictly better to send it
as an `Raw_Block`. However, blocks are not entirely independent, and it can
make sense to pay the cost of encoding custom entropy tables in a block, even
if that pushes that block size over the size of the data it represents,
because those tables can be re-used by subsequent blocks.
Finally, as far as I can tell, this restriction in the spec is not currently
enforced in any Zstandard implementation, nor has it ever been. This change
should therefore be safe to make.

benchfn dependencies reduced to only timefn
...
benchfn used to rely on mem.h, and util,
which in turn relied on platform.h.
Using benchfn outside of zstd required to bring all these dependencies.
Now, dependency is reduced to timefn only.
This required to create a separate timefn from util,
and rewrite benchfn and timefn to no longer need mem.h.
Separating timefn from util has a wide effect accross the code base,
as usage of time functions is widespread.
A lot of build scripts had to be updated to also include timefn.
