chore: Inline BUILD.bazel dependency vars under governance-team

[nmattia]

Inline module-level DEPENDENCIES, MACRO_DEPENDENCIES, etc variables into their consuming targets. Where inlining made a wasm32-unknown-unknown select redundant (test-only targets or canister-only targets), the select is also dropped.

Pull request overview

This PR refactors a set of Bazel BUILD.bazel files (primarily under NNS/SNS/registry/nervous_system) by inlining previously shared module-level dependency variables (e.g., DEPENDENCIES, DEV_DEPENDENCIES, MACRO_DEPENDENCIES, ALIASES) directly into the targets that consume them. In a few places it also removes wasm32-unknown-unknown select() blocks that are now redundant due to the dependency lists being used only by host-only test targets.

Changes:

• Inlined proc_macro_deps and deps lists into individual rust_* targets; removed now-unused module-level dependency variables.
• Removed ALIASES = {} and corresponding aliases = ALIASES assignments where they were effectively no-ops.
• Simplified some select({ wasm32: ..., default: ... }) blocks where the selection no longer affects any wasm-built targets.
