all: simplify wasm-tools-go dependency

- add internal/wasm-tools/go.mod file to depend on wasm-tools-go
- copy package cm into src/internal/cm
- remove wasm-tools-go "vendor" submodule

internal/tools: fix typo

go.{mod,sum}, internal/tools: add wit-bindgen-go to tools

GNUmakefile: use go run for wit-bindgen-go

GNUmakefile: add tools target to go:generate tools binaries in internal/tools

GNUmakefile: add .PHONY for lint and spell

GNUmakefile, internal/cm: vendor package cm into internal/cm

go.{mod,sum}: update wasm-tools-go to v0.1.4

internal/wasi: use internal/cm package

remove submodule src/vendor/github.com/ydnar/wasm-tools-go

GNUmakefile: add comment documenting what wasi-cm target does

go.{mod,sum}: remove toolchain; go mod tidy

go.mod: revert to Go 1.19

go.mod: go 1.19

go.{mod,sum}, internal/{tools,wasm-tools}: revert root go.mod file to go1.19

Create a wasm-tools specific module that can require go1.22 for wasm-tools-go.
