refactor(web): use encoding_rs for text encoding (#10844)
This commit removes all JS based text encoding / text decoding. Instead
encoding now happens in Rust via encoding_rs (already in tree). This
implementation retains stream support, but adds the last missing
encodings. We are incredibly close to 100% WPT on text encoding now.

This should reduce our baseline heap by quite a bit.

Tools

Documentation for various tooling in support of Deno development.

format.js

This script will format the code (currently using dprint, rustfmt). It is a prerequisite to run this before code check in.

To run formatting:

deno run --allow-read --allow-write --allow-run --unstable ./tools/format.js

lint.js

This script will lint the code base (currently using dlint, clippy). It is a prerequisite to run this before code check in.

To run linting:

deno run --allow-read --allow-write --allow-run --unstable ./tools/lint.js

Tip: You can also use cargo to run the current or pending build of the deno executable

cargo run -- run --allow-read --allow-write --allow-run --unstable ./tools/<script>

flamebench.js

flamebench.js facilitates profiling and generating flamegraphs from benchmarks.

General usage:

 ./tools/flamebench.js
flamebench <bench_name> [bench_filter]

Available benches:
op_baseline
ser
de

To profile the op_baseline bench, run ./tools/flamebench.js op_baseline, this will run all 3 benches in `op_baseline.

Often when profiling/optimizing, you'll want to focus on a specific sub-bench, flamebench supports a bench/test filter arg like the regular cargo commands. So you can simply run ./tools/flamebench.js op_baseline bench_op_async or ./tools/flamebench.js op_baseline bench_op_nop to profile specific benches.

Tip: the [bench_filter] argument doesn't have to be an exact bench name, you can use a shorthand or a partial match to profile a group of benches, e.g: ./tools/flamebench.js de v8
