Make js-feature non default

[mattsse]

Describe the feature

js-tracer is currently always enabled

reth/crates/rpc/rpc/Cargo.toml

Line 30 in f425521

revm-inspectors = { workspace = true, features = ["js-tracer"] }

we can avoid this by

1. make this non-default:

   reth/crates/rpc/rpc-eth-types/Cargo.toml

   Line 62 in f425521

   default = ["js-tracer"]

2. introduce js-tracer feature on rpc that enables:

   reth/crates/rpc/rpc/Cargo.toml

   Line 30 in f425521

   revm-inspectors = { workspace = true, features = ["js-tracer"] }

   and feature gate support for js tracer

Thank you!
Can we also make it optional in the node level as well, e.g. in the rpc-builder?

[mattsse]

we could, we could push it down to node-builder or ethereum/op-node level

I'd appreciate an issue for this and perhaps some context if you can share
