Build PG 14 and above with lz4 compression

[robe2]

Introduced in PG 14 is lz4 compression. I'm revising my mingw64 build to build with lz compression.
I haven't checked what is entailed on Linux. On mingw64 I had to install the lz4 libraries and change my postgresql ./configure

to have:

 --with-lz4

This broke my PostGIS building, cause then it tried to drag in Lz4 and couldn't find it. Still fixing that before I make similar change on Winnie
