WIP: Use `xtask` as build system (#2012)

* xtask: Implement a new build system

xtask is a cargo alias that is used to extend the cargo build system
with custom commands. For an introduction to xtask, see here:
https://github.com/matklad/cargo-xtask/

The idea is that instead of writing makefiles, xtask requires no
additional dependencies except `cargo` and `rustc`, which must be
available to build the project anyway.

This commit provides a basic implementation of the `build` and `test`
subcommands.

* xtask/deps: Add 'which'

* xtask/test: Handle error when cargo not found

* xtask/flags: Add more commands

to perform different useful tasks. Includes:

- clippy
- format
- "make" (composite)
- "install" (composite)

Also add more options to `build` to selectively compile plugins or leave
them out entirely.

* xtask/main: Return error when cargo not found

* xtask/build: Add more subtasks

- `wasm_opt_plugins` and
- `manpage`

that perform other build commands. Add thorough documentation on what
each of these does and also handle the new `build` cli flags
appropriately.

* xtask/clippy: Add job to run clippy

* xtask/format: Add job to run rustfmt

* xtask/pipeline: Add composite commands

that perform multiple atomic xtask commands sequentially in a pipeline
sort of fashion.

* xtask/deps: Pin dependencies

* xtask/main: Integrate new jobs

and add documentation.

* xtask: Implement 'dist'

which performs an 'install' and copies the resulting zellij binary along
with some other assets to a `target/dist` folder.

* cargo: Update xflags version

* xtask: Measure task time, update tty title

* xtask: Update various tasks

* xtask: wasm-opt plugins in release builds

automatically.

* xtask/build: Copy debug plugins to assets folder

* xtask: Add 'run' subcommand

* xtask: Add arbitrary args to test and run

* xtask: Rearrange CLI commands in help

* xtask: Add deprecation notice

* docs: Replace `cargo make` with `xtask`

* github: Use `xtask` in workflows.

* xtask: Add support for CI commands

* xtask: Streamline error handling

* github: Use new xtask commands in CI

* xtask: Add 'publish' job

* xtask/publish: Add retry when publish fails

* xtask: Apply rustfmt

* xtask: Refine 'make' deprecation warning

* xtask: add task to build manpage

* contributing: Fix e2e commands

* xtask/run: Add missing `--`

to pass all arguments following `xtask run` directly to the zellij
binary being run.

* xtask: Stay in invocation dir

and make all tasks that need it change to the project root dir
themselves.

* xtask/run: Add `--data-dir` flag

which will allow very quick iterations when not changing the plugins
between builds.

* xtask/ci: Install dependencies without asking

* utils: Allow including plugins from target folder

* utils/assets: Reduce asset map complexity

* utils/consts: Update asset map docs

* xtask: Fix plugin includes

* xtask/test: Build plugins first

because the zellij binary needs to include the plugins.

* xtask/test: Fix formatting

* xtask: Add notice on how to disable it
