Fix bindgen-cli support link static libclang

[inevity]

Before we link bindgen with default features including runtime libclang.
After the pr, we can build bindgen-cli with no-defautl-features to link static libclang, such as 'cargo install --locked --no-default-features -F static,logging --path .'
If not , runtime and static feature will be confict reported by the clang-sys.

Thanks for this!

Is there a test for this?

Look like the repo did not have a ci? I just test this with change:"bindgen = { path = "../bindgen", version = "=0.65.1", default-features = false, features = ["logging", "which-rustfmt", "__cli", "experimental"] }".
And the pr using the change "bindgen = { path = "../bindgen", version = "=0.65.1", default-features = false, features = [ "__cli", "experimental"] }" which did not have feature:logging and which-rustfmt did not test

yeah I think this was an oversight when we migrated bindgen to workspaces as we use the dynamic library for clang by default, so unless you've been trying to install bindgen-cli with static support by explicitly passing --features=static it is unlikely that you've noticed this.
