[PATCH] ci: build with MSVC in GHA

[David Marchand]

Add a build target in Windows 2022 for MSVC.

Loading MSVC environment and having successive commands in a single
(cmd or pwsh) shell does not seem to correctly report if one of the
commands failed.
For now, load MSVC environment and run commands in separate shells.
