9dd6efb7e4 wasm linker: fix TLS data segments
fix calculation of alignment and size

include __tls_align and __tls_size globals along with __tls_base

include them only if the TLS segment is emitted

wasm: gc fixes and re-enable linker tests
Certain symbols were left unmarked, meaning they would not be emit into
the final binary incorrectly. We now mark the synthetic symbols to ensure
they are emit as they are already created under the circumstance they're
needed for. This also re-enables disabled tests that were left disabled
in a previous merge conflict.
Lastly, this adds the shared-memory test to the test harnass as it was
previously forgotten and therefore regressed.

142471fcc4 zig build system: change target, compilation, and module APIs
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.

update linker tests
This updates all linker tests to include `no_entry` as well as changes
all tests to executable so they do not need to be updated later when
the in-house WebAssembly linker supports dynamic libraries.

wasm-linker: create TLS Wasm globals correctly
Previously, they were only created when we had any TLS segment.
This meant that while the symbol existed, the global itself wouldn't.
The result of this was a crash during symbol names writing as it
would attempt to write the symbol name of a global that didn't exist.
Now we always create them, and instead update its `init` value during
`setupMemory`.

In the future, the entire symbol (and global) will be removed by
the garbage collector.
