This commit removes all the scripts located in src/tools/msvc/ to build
PostgreSQL with Visual Studio on Windows, meson becoming the recommended
way to achieve that. The scripts held some information that is still
relevant with meson, information kept and moved to better locations.
Comments that referred directly to the scripts are removed.
All the documentation still relevant that was in install-windows.sgml
has been moved to installation.sgml under a new subsection for Visual.
All the content specific to the scripts is removed. Some adjustments
for the documentation are planned in a follow-up set of changes.

This issue can be reproduced by running `make dist` from the root of the
tree. Error introduced in fcb21b3, where additions of links in
installation.sgml require custom rules in standalone-profile.xsl to make
sure that ./INSTALL is generated correctly for the distribution tarball,
where links are replaced by equivalent terms from the profile file
changed by this commit.

The logic is implemented so as there can be a choice in the compression
used when building a WAL record, and an extra per-record bit is used to
track down if a block is compressed with PGLZ, LZ4 or nothing.
wal_compression, the existing parameter, is changed to an enum with
support for the following backward-compatible values:
- "off", the default, to not use compression.
- "pglz" or "on", to compress FPWs with PGLZ.
- "lz4", the new mode, to compress FPWs with LZ4.
Benchmarking has showed that LZ4 outclasses easily PGLZ. ZSTD would be
also an interesting choice, but going just with LZ4 for now makes the
patch minimalistic as toast compression is already able to use LZ4, so
there is no need to worry about any build-related needs for this
implementation.

"make dist", in charge of creating a distribution tarball, failed when
attempting to generate ./INSTALL as a new reference added to
guc-default-toast-compression on the documentation for the installation
details was not getting translated properly to plain text. Like all the
other link references on this page, this adds a new entry to
standalone-profile.xsl to allow the generation of ./INSTALL to finish
properly.
Oversight in 02a93e7, per buildfarm member guaibasaurus.
Previously, we created a variant of the installation instructions for
producing the plain-text INSTALL file by marking up certain parts of
installation.sgml using SGML parameterized marked sections. Marked
sections will not work anymore in XML, so before we can convert the
documentation to XML, we need a new approach.
DocBook provides a "profiling" feature that allows selecting content
based on attributes, which would work here. But it imposes a noticeable
overhead when building the full documentation and causes complications
when building some output formats, and given that we recently spent a
fair amount of effort optimizing the documentation build time, it seems
sad to have to accept that.
So as an alternative, (1) we create our own mini-profiling layer that
adjusts just the text we want, and (2) assemble the pieces of content
that we want in the INSTALL file using XInclude. That way, there is no
overhead when building the full documentation and most of the "ugly"
stuff in installation.sgml can be removed and dealt with out of line.
