Disable pnpm post install scripts and fix pnpm audit dependencies

[texodus]

• Moves all project dependencies and devDependencies to reference entries in the pnpm catalog (except @finos/perspective-jupyterlab, for which @jupyterlab/builder helpfully has custom dependency parsing logic).
• Updates many/most dependencies to latest versions. These are mostly dev/build/test dependencies - see pnpm-workspace.yaml.
• Removes a lot of build dependencies of questionable necessity.
• Dedupes a few dev/build/test dependencies with multiple resolved versions.
• Dedupes ~50kb of duplicate modules in the @finos/perspective-viewer-d3fc package.
• Fixes all pnpm audit reports and all but three "deprecated" warnings (all three of which are dependencies of @jupyterlab/builder, 'nat).
• Disables build-scripts for default pnpm install.
• Removes most inline bash scripting in package.json scripts tags.
• Removes a few of perspective internal build tools in favor of zx
