Acts as a replacement for `addSharedLibrary` and `addStaticLibrary`, but
linking mode can be changed more easily in build.zig, for example:
In library:
```zig
const linkage = b.option(std.builtin.LinkMode, "linkage", "Link mode for a foo_bar library") orelse .static; // or other default
const lib = b.addLibrary(.{
.linkage = linkage,
.name = "foo_bar",
.root_module = mod,
});
```
In consumer:
```zig
const dep_foo_bar = b.dependency("foo_bar", .{
.target = target,
.optimize = optimize,
.linkage = .static // or dynamic
});
mod.linkLibrary(dep_foor_bar.artifact("foo_bar"));
```
It also matches nicely with `linkLibrary` name.

This was the cause of aarch64-windows shared libraries causing "bad image" errors
during load-time linking. I also re-enabled the tests that were surfacing this bug.
Introduce the concept of "target query" and "resolved target". A target
query is what the user specifies, with some things left to default. A
resolved target has the default things discovered and populated.
In the future, std.zig.CrossTarget will be rename to std.Target.Query.
Introduces `std.Build.resolveTargetQuery` to get from one to the other.
The concept of `main_mod_path` is gone, no longer supported. You have to
put the root source file at the module root now.
* remove deprecated API
* update build.zig for the breaking API changes in this branch
* move std.Build.Step.Compile.BuildId to std.zig.BuildId
* add more options to std.Build.ExecutableOptions, std.Build.ObjectOptions,
std.Build.SharedLibraryOptions, std.Build.StaticLibraryOptions, and
std.Build.TestOptions.
* remove `std.Build.constructCMacro`. There is no use for this API.
* deprecate `std.Build.Step.Compile.defineCMacro`. Instead,
`std.Build.Module.addCMacro` is provided.
- remove `std.Build.Step.Compile.defineCMacroRaw`.
* deprecate `std.Build.Step.Compile.linkFrameworkNeeded`
- use `std.Build.Module.linkFramework`
* deprecate `std.Build.Step.Compile.linkFrameworkWeak`
- use `std.Build.Module.linkFramework`
* move more logic into `std.Build.Module`
* allow `target` and `optimize` to be `null` when creating a Module.
Along with other fields, those unspecified options will be inherited
from parent `Module` when inserted into an import table.
* the `target` field of `addExecutable` is now required. pass `b.host`
to get the host target.
These functions are problematic in light of dependencies because they
run and install, respectively, for the *owner* package rather than for
the *user* package. By removing these functions, the build script is
forced to provide the *Build object to associate the new step with,
making everything less surprising.
Unfortunately, this is a widely breaking change.
see #15079
Positional shared library arguments were not being detected as causing
dynamic linking, resulting in invalid linker lines. LLD did not have an
error message for this when targeting x86_64-linux but it did emit an
error message when targeting aarch64-linux, which is how I noticed the
problem.
This surfaced an error having to do with fifo.pipe() in the cat example
which I did not diagnose but solved the issue by doing the revamp that
was already overdue for that example.
It appears that the zig-window project was exploiting the previous
behavior for it to function properly, so this prompts the question, is
there some kind of static/dynamic executable hybrid that the compiler
should recognize? Unclear - but we can discuss that in #7240.
