[NS 3] TypeScript: server module runtime API for module mounts

[aasoni]

Description of Changes

Changes the typescript runtime and query builder to handle mounted sub-modules.

API and ABI breaking changes

No

Expected complexity level and risk

4 - Changes in runtime.ts are quite extensive as they require each dispatch (table/reducer/procedure/view) to go through mounts logic.

Testing

Beyond the typescript tests in this PR, the following testing was done

Module:

• root module can import another module and mount it with a namespace under its schema
• root module and submodule can have the same function and table names without conflicting
• ctx.db.lib.lib_table is readable/writable inside root module reducer
• ctx.db.lib.lib_table is readable/writable inside root module procedure withTx block
• library_reducer(ctx.as.lib) is callable inside root module reducer

Client

• Client can subscribe to lib.library_table
• Client can subscribe to lib.library_view
• Client can call lib/library_reducer
• Client can call lib/library_procedure
• Client can subscribe to lib.sublib.sublib_table
• Client can subscribe to lib.sublib.sublib_view
• Client can call lib/sublib/sublib_reducer
• Client can call lib/sublib/sublib_procedure

CLI

• CLI can subscribe to lib.library_table
• CLI can subscribe to lib.library_view
• CLI can call lib/library_reducer
• CLI can call lib/library_procedure
• CLI can subscribe to lib.sublib.sublib_table
• CLI can subscribe to lib.sublib.sublib_view
• CLI can call lib/sublib/sublib_reducer
• CLI can call lib/sublib/sublib_procedure

Migration

• Module migrates without issue from having a submodule to not having a submodule
• Module migrates without issue from not having a submodule to having a submodule
• Module migrates without issue when having a submodule and root module change occurs (change reducer signature, add table, add column with default, change reducer function body, change index)
• Module migrates without issue when having a submodule and a submodule change occurs (change reducer signature, add table, add column with default, change reducer function body, change index)

Commit Log

• Module loads fine from commit log
• Module snapshot is created without issue
• Module loads fine from snapshot
