Compile resx file into binary resource file for use in AssemblyAction

[jrbeverly]

Compiles a single resx file into a common language runtime binary resource file.

Example usage:

csharp_resx(
    name = "hello.resources.mystrings",
    src = "Strings.resx",
    identifier = "Hello.Strings.resources",
)

There a couple of things I'll mention here:

• ResX files have a lot of cases that I think should be tested (multiple resx files, embedded files, identifier/out parameters, etc)
• A target_framework is necessary for the csproj to compile

Resolves #10 , #77

Just cursory nits. Haven't dug into implementation too much yet.

I have simplified the work done down to two rules, and moved the C++ compilation wrapper into the bash wrapper. This wrapper doesn't have as much going on (besides the boilerplate runfiles code).

I did discover something while working on windows, and that is that there exists a segmentation fault in the dotnetw wrapper. So I'll creating an issue to try to resolve that. I suspect it is related to the dotnet_argv that are passed in from argv. I suspect it needs to be copied rather than just reference.

Sorry in the delay getting back to this, I'll go through it on the weekend when I have some quiet time :)

While doing the housekeeping on some of these PRs, I noticed that with the latest release of the dotnet SDK 3.1.100, it introduced the expectation for project.assets.json.

That was failing the resx compilation due to its usage of dotnet build. Based on a quick search, I suspect this'll impact the current implementation of resx.
