Vcpkg manifest

[mfellows]

Pull Request Template

Description

Added a vcpkg manifest file (vcpkg.json) and VS2019 and 2022 batch files for setting up vcpkg and building all dependencies in manifest mode - this allows us to use a slightly newer May 2022 vcpkg and finally upgrade to GDAL 3.4.3.

Does not break the previous build procedure, which can still be used.

Type of change

• New feature (non-breaking change which adds functionality)

How Has This Been Tested?

Built on two different local machines, both running Windows 10, one with VS2022 and the other with VS2019.
