langref: Make pointer_coerce_const_optional test less obfuscated

This test was originally introduced in 5f38d6e2e97829ed74f06a96b5d07a2c68516063, where it looked like this: test "cast *[1][*]const u8 to [*]const ?[*]const u8" { const window_name = [1][*]const u8{c"window name"}; const x: [*]const ?[*]const u8 = &window_name; assert(mem.eql(u8, std.cstr.toSliceConst(x[0].?), "window name")); } Over the years, this has become more and more obfuscated, to the point that the verbosity of the `expect` call overshadows the point of the example. This commit intends to update this test to match the spirit of the original version of the test, while shedding the obfuscation.
