Zig's format system is flexible enough to add custom formatters. This PR removes the new z/Z format specifiers that were added for printing Zig identifiers and replaces them with custom formatters.

This is convenient for debugging purposes, as well as simplifying the
caching system since executable basenames will not conflict with their
corresponding object files.

* change some {} to be {s} to gain type safety
* fix libraries being libfoo.lib instead of foo.lib for COFF
* when linking mingw-w64, add the "always link" libs so that we
generate DLL import .lib files for them as the linker code relies on.
* COFF LLD linker does not support -r so we do a file copy as an
alternative to the -r thing that ELF linking does.
I will file an issue for the corresponding TODO upon merging this
branch, to look into an optimization that possibly elides this copy
when the source and destination are both cache directories.
* add a CLI error message when trying to link multiple objects into one
and using COFF object format.

still TODO is the task of creating import .lib files for DLLs on the fly
both for -lfoo and for e.g. `extern "kernel32"`

* Don't try to generate C header files yet since it will only cause a
crash saying the feature is unimplemented.
* Rename the CLI options for release modes to use the `-O` prefix to
match C compiler precedent. Options are now `-ODebug`,
`-OReleaseFast`, `-OReleaseSafe`, `-OReleaseSmall`. The optimization
mode matches the enum tags of std.builtin.Mode. It is planned to, at
some point, rename std.builtin.Mode to std.builtin.OptimizationMode
and modify the tags to be lower case to match the style convention.
- Update build.zig code to support this new CLI.
* update std.zig.binNameAlloc to support an optional Version and update
the implementation to correctly deal with dynamic library version
suffixes.

* std.cache_hash exposes Hasher type
* std.cache_hash makes hasher_init a global const
* std.cache_hash supports cloning so that clones can share the same
open manifest dir handle as well as fork from shared hasher state
* start to populate the cache_hash for stage2 builds
* remove a footgun from std.cache_hash add function
* get rid of std.Target.ObjectFormat.unknown
* rework stage2 logic for resolving output artifact names by adding
object_format as an optional parameter to std.zig.binNameAlloc
* support -Denable-llvm in stage2 tests
* Module supports the use case when there are no .zig files
* introduce c_object_table and failed_c_objects to Module
* propagate many new kinds of data from CLI into Module and into
linker.Options
* introduce -fLLVM, -fLLD, -fClang and their -fno- counterparts.
closes #6251.
- add logic for choosing when to use LLD or zig's self-hosted linker
* stub code for implementing invoking Clang to build C objects
* add -femit-h, -femit-h=foo, and -fno-emit-h CLI options

- This avoids having multiple `init()` functions for every combination
of optional parameters
- The API is consistent across all hash functions
- New options can be added later without breaking existing applications.
For example, this is going to come in handy if we implement parallelization
for BLAKE2 and BLAKE3.
- We don't have a mix of snake_case and camelCase functions any more, at
least in the public crypto API
Support for BLAKE2 salt and personalization (more commonly called context)
parameters have been implemented by the way to illustrate this.

Instead of having all primitives and constructions share the same namespace,
they are now organized by category and function family.
Types within the same category are expected to share the exact same API.

* Introduce the concept of anonymous Decls
* Primitive Hello, World with inline asm works
* There is still an unsolved problem of how to manage ZIR instructions
memory when generating from AST. Currently it leaks.

Zig now supports a more fine-grained sense of what is native and what is
not. Some examples:
This is now allowed:
-target native
Different OS but native CPU, default Windows C ABI:
-target native-windows
This could be useful for example when running in Wine.
Different CPU but native OS, native C ABI.
-target x86_64-native -mcpu=skylake
Different C ABI but otherwise native target:
-target native-native-musl
-target native-native-gnu
Lots of breaking changes to related std lib APIs.
Calls to getOs() will need to be changed to getOsTag().
Calls to getArch() will need to be changed to getCpuArch().
Usage of Target.Cross and Target.Native need to be updated to use
CrossTarget API.
`std.build.Builder.standardTargetOptions` is changed to accept its
parameters as a struct with default values. It now has the ability to
specify a whitelist of targets allowed, as well as the default target.
Rather than two different ways of collecting the target, it's now always
a string that is validated, and prints helpful diagnostics for invalid
targets. This feature should now be actually useful, and contributions
welcome to further improve the user experience.
`std.build.LibExeObjStep.setTheTarget` is removed.
`std.build.LibExeObjStep.setTarget` is updated to take a CrossTarget
parameter.
`std.build.LibExeObjStep.setTargetGLibC` is removed. glibc versions are
handled in the CrossTarget API and can be specified with the `-target`
triple.
`std.builtin.Version` gains a `format` method.

(include and lib search paths)
The detection of native system paths is self-hosted.

that's all this commit does. further commits will fix cli flags and
such.
