gpu: fix alignment issues with getMappedRange, getConstMappedRange (#223) 
fixes alignment issues with getMappedRange, getConstMappedRange

Prior to this change `getMappedRange` and `getConstMappedRange` would not handle alignment to `COPY_BUFFER_ALIGNMENT` for users, and so invocation could result in an unhelpful error message:

```
    thread 254201 panic: attempt to use null value
    .../mach/gpu/src/NativeInstance.zig:1721:42: 0x480747
    in .gpu.NativeInstance.buffer_vtable.getMappedRange (game)
            return @ptrCast([*c]u8, range.?)[0..size];
					 ^
```

To address this:

1. Ensure we always request a 4-byte aligned buffer when `createBuffer` is called.
2. Ensure we always map 4-byte aligned buffers.

build: never use pkg-config to link system libraries (#217) 
Every library we want to link against is either provided by the Zig
toolchain or part of our SDK. Therefore, using pkg-config to link
against libraries on the host system is never what we intend.

To fix this, use linkSystemLibraryName() everywhere instead of
linkSystemLibrary() as the latter integrates with pkg-config while the
former just passes -lfoo to the zig compiler.

In combination with Zig commit 38d6e1d8a8 fixing an std.build bug,
this change fixes the linking of the necessary X11 libraries on my
x86_64 glibc based Void Linux system.
