Install PHP to C:\tools\php. This fixes the AppVeyor tests, because
they were looking in C:\tools\php73, but the Chocolatey package has
recently moved to 7.4.
For some reason, possibly the new images that AppVeyor rolled out on Oct 22,
our AppVeyor tests now fail immediately, with msbuild complaining that there
are multiple solutions in the repository.
Address this by not using the default AppVeyor build section, but calling
msbuild ourselves explicitly in the build_script section. This way, we can
specify which .slns we want to build. I have specified the runtime and
runtime-testsuite Antlr4.vs2013.slns; the other ones didn't work for me in
this configuration.
Also, these builds were previously running with low / zero logging. As
far as I can tell, this gave AppVeyor no way to know whether the build has
succeeded or not. It certainly gives no way to diagnose any failures that do
occur. I have dialed the logging up on everything.
Also, remove the os declaration. That appears to be well out of date, and
isn't on AppVeyor's list of images any more. I presume that we've been
using their default image for some time.
