Add NetFx .NET compatibility check for MSI (#262)

Adds new custom element in NetFx extension for running NetCoreCheck.exe
tool from within the MSI installer - `<netfx:DotNetCompatibilityCheck
/>`. The checks are run before evaluating launch conditions, so their
results can be used in those conditions. There is no limitation on the
number of checks that can be run, so installer may query various
runtimes on different platforms and versions and with different roll
forward policies.
