chore: remove perl, make and local docs. (#476)

Remove the dependencies on perl and make.

inline.pl is replaced by tools/gen-jscore and token/tokenfmt is replaced
by tools/gen-tokens which are both golang text/template utilities.

gen-jscore uses property ordering that matches chromes output ordering
adding missing properties to the Error types.

Local generated documentation have been removed as https://pkg.go.dev/
is more feature rich.

The use of make has been removed as the functionality is now replicated by
standard golang tools go test ./... and go generate ./... as well as integrated
into github actions.
