zig init: simplify templating logic (#24170)
and also rename `advancedPrint` to `bufferedPrint` in the zig init templates

These are left overs from my previous changes to zig init.

The new templating system removes LITNAME because the new restrictions on package names make it redundant with NAME, and the use of underscores for marking templated identifiers lets us template variable names while still keeping zig fmt happy.

1116d88196 zig init: add new --strip flag and improve template files
This commit introduces a new flag to generate a new Zig project using
`zig init` without comments for users who are already familiar with the
Zig build system.

Additionally, the generated files are now different. Previously we would
generate a set of files that defined a static library and an executable,
which real-life experience has shown to cause confusion to newcomers.

The new template generates one Zig module and one executable both in
order to accommodate the two most common use cases, but also to suggest
that a library could use a CLI tool (e.g. a parser library could use a
CLI tool that provides syntax checking) and vice-versa a CLI tool might
want to expose its core functionality as a Zig module.

All references to C interoperability are removed from the template under
the assumption that if you're tall enough to do C interop, you're also
tall enough to find your way around the build system. Experienced users
will still be able to use the current template and adapt it with minimal
changes in order to perform more advanced operations. As an example, one
only needs to change `b.addExecutable` to `b.addLibrary` to switch from
generating an executable to a dynamic (or static) library.

d6a88ed74d introduce package id and redo hash format again
Introduces the `id` field to `build.zig.zon`.

Together with name, this represents a globally unique package
identifier. This field should be initialized with a 16-bit random number
when the package is first created, and then *never change*. This allows
Zig to unambiguously detect when one package is an updated version of
another.

When forking a Zig project, this id should be regenerated with a new
random number if the upstream project is still maintained. Otherwise,
the fork is *hostile*, attempting to take control over the original
project's identity.

`0x0000` is invalid because it obviously means a random number wasn't
used.

`0xffff` is reserved to represent "naked" packages.

Tracking issue #14288

Additionally:

* Fix bad path in error messages regarding build.zig.zon file.
* Manifest validates that `name` and `version` field of build.zig.zon
  are maximum 32 bytes.
* Introduce error for root package to not switch to enum literal for
  name.
* Introduce error for root package to omit `id`.
* Update init template to generate `id`
* Update init template to populate `minimum_zig_version`.
* New package hash format changes:
  - name and version limited to 32 bytes via error rather than truncation
  - truncate sha256 to 192 bits rather than 40 bits
  - include the package id

This means that, given only the package hashes for a complete dependency
tree, it is possible to perform version selection and know the final
size on disk, without doing any fetching whatsoever. This prevents
wasted bandwidth since package versions not selected do not need to be
fetched.

d789f1e5cf fuzzer: write inputs to shared memory before running
breaking change to the fuzz testing API; it now passes a type-safe
context parameter to the fuzz function.

libfuzzer is reworked to select inputs from the entire corpus.

I tested that it's roughly as good as it was before in that it can find
the panics in the simple examples, as well as achieve decent coverage on
the tokenizer fuzz test.

however I think the next step here will be figuring out why so many
points of interest are missing from the tokenizer in both Debug and
ReleaseSafe modes.

does not quite close #20803 yet since there are some more important
things to be done, such as opening the previous corpus, continuing
fuzzing after finding bugs, storing the length of the inputs, etc.

f645022d16 merge zig init-exe and zig init-lib into zig init
Instead of `zig init-lib` and `zig init-exe`, now there is only
`zig init`, which initializes any of the template files that do not
already exist, and makes a package that contains both an executable and
a static library. The idea is that the user can delete whatever they
don't want. In fact, I think even more things should be added to the
build.zig template.
