Both `core` and `alloc` have their `cfgs` (such as `no_rc`) missing
in `rust-project.json`.
To remedy this, pass the flags to `generate_rust_analyzer.py` for
them to be added to a dictionary where each key corresponds to
a crate and each value to a list of `cfg`s. The dictionary is then
used to pass the `cfg`s to each crate in the generated file (for
`core` and `alloc` only).

Adds support for out-of-tree rust modules to use the `rust-analyzer`
make target to generate the rust-project.json file.
The change involves adding an optional parameter `external_src` to the
`generate_rust_analyzer.py` which expects the path to the out-of-tree
module's source directory. When this parameter is passed, I have chosen
not to add the non-core modules (samples and drivers) into the result
since these are not expected to be used in third party modules. Related
changes are also made to the Makefile and rust/Makefile allowing the
`rust-analyzer` target to be used for out-of-tree modules as well.

More complex drivers might want to use modules to organize their Rust
code, but those module folders do not need a Makefile.
generate_rust_analyzer.py currently crashes on those. Fix it so that a
missing Makefile is silently ignored.

The `build_error` crate provides a function `build_error` which
will panic at compile-time if executed in const context and,
by default, will cause a build error if not executed at compile
time and the optimizer does not optimise away the call.
The `CONFIG_RUST_BUILD_ASSERT_ALLOW` kernel option allows to
relax the default build failure and convert it to a runtime
check. If the runtime check fails, `panic!` will be called.
Its functionality will be exposed to users as a couple macros in
the `kernel` crate in the following patch, thus some documentation
here refers to them for simplicity.

The `generate_rust_analyzer.py` script generates the configuration
file (`rust-project.json`) for rust-analyzer.
rust-analyzer is a modular compiler frontend for the Rust language.
It provides an LSP server which can be used in editors such as
VS Code, Emacs or Vim.
