internal: port anymap
## Description
- The anymap crate has been ported. During this process, unnecessary features for rust-analyzer have been removed.
- From the tests that were checking the existing licenses, the anymap license (`BlueOak-1.0.0 OR MIT OR Apache-2.0`) has been removed.
## Requests
- While porting the code this time, I have tried to respect the original author's intentions and have kept the comments/codes as much as possible. Please don't hesitate to tell me if you think the comments/codes also need to be appropriately modified.
- If there are any necessary changes regarding the licensing or anything else, please let me know so I can fix them.
## Issue
https://github.com/rust-lang/rust-analyzer/issues/15500
Implement builtin#format_args, using rustc's format_args parser
`format_args!` now expands to `builtin#format_args(template, args...)`, the actual expansion now instead happens in lowering where we desugar this expression by using lang paths.
As a bonus, we no longer need to evaluate `format_args` as an eager macro which means less macro expansions overall -> less cache thrashing!

internal: unpin serde
Serde no longer uses blobs as of
https://github.com/serde-rs/serde/pull/2590
As such, there's no longer need for us to pin it.
Note that this doesn't upgrade serde version we use: I am fairly confident that the blobs are already there are fine, and now I am fairly confident that all future versions of serde will be fine as well.

serde 1.0.172 and up rely on opaque non-reproducible binary blobs to
function, explicitly not providing a library-level opt-out.
This is problematic for two reasons:
- directly, unauditable binary blobs are a security issue.
- indirectly, it becomes much harder to predict future behaviors of the
crate.
As such, I am willing to go on a limb here and forbid building
rust-analyzer with those versions of serde. Normally, my philosophy is
to defer the choice to the end user, but it's also a design constraint
of rust-analyzer that we don't run random binaries downloaded from the
internet without explicit user's concent.
Concretely, this upper-bounds serde for both rust-analyzer workspace, as
well as the lsp-server lib.
See https://github.com/serde-rs/serde/issues/2538 for wider context.
Map our diagnostics to rustc and clippy's ones
And control their severity by lint attributes `#[allow]`, `#[deny]` and ... .
It doesn't work with proc macros and I would like to fix that before merge but I don't know how to do it.
Split out project loading capabilities from rust-analyzer crate
External tools currently depend on the entire lsp infra for no good reason so let's lift that out so those tools have something better to depend on
