libvault: fix import of Version + decrease min Visual Studio Version + many small fixes

[SpaceIm]

• fix import of Version (from conan import Version was illegal and breaks in conan 2.0.10)
• use export_conandata_patches()
• remove useless VirtualBuildEnv generator (there is no build requirements in this recipe
• bump libcurl
• remove useless catch2 in requirements (it's used for tests, but tests are disabled...)
• add package_type
• fix min Visual Studio (it was ... 19, which doesn't make sense) and add min version for msvc
• use self.settings instead of self.info.settings in validate()
• remove useless CMakeLists wrapper (it had old conan v1 stuff with conan_basic_setup() and was not used at all...)
• add a layout
• add libm to system libs on Linux & FreeBSD only

---

• I've read the contributing guidelines.
• I've used a recent Conan client version close to the currently deployed.
• I've tried at least one configuration locally with the conan-center hook activated.

Last PR of libvault is #14498, far before v2 pipeline. There might be more fixes needed to pass this pipeline.

libvault shared, msvc:

ERROR: libvault/0.52.0 (test package): Error in test() method, line 19
	self.run(bin_path, run_environment=True)
	ConanException: Error 3221225785 while executing bin\test_package

Ok so the problem on Windows is that there is a Vault.dll system library in System32 (found first by runtime loader), and libvault creates vault.dll file, it's an unfortunate name.
