🍃 BAZEL progress

• Bazel build workflow is now successfuly running on github actions using github's linux runners. The build produces a valid downloadable artefact containing all GUI static assets.
  https://github.com/enso-org/enso/actions/workflows/bazel-build.yml
• Split the gui environment configuration away from the main build artifacts. The same vite command output can be easily transformed into testing or production package without rebuilding. This is done in preparation for "promote to production" workflow, guaranteeing that exactly the same code is used across testing builds and actual releases.
• Completely removed the dependency on locally installed rust or wasm toolchains (e.g. wasm-bindgen), even when building the GUI locally. All rust-related artifacts are built using bazel even in local development.

Remaining work:

• Some dashboard tests currently fail, and that need to be addressed.
• The bazel build currently fails on Windows, which also affects our CI runners. This need to be sorted before merging is possible.
• Merging this PR proves to be problematic due to frequent merge conflicts, which in turn introduce linting and testing errors.

Parser improvements: "What is a function, really?"

## ICON data_input
   Returns a new Connection with the specified database set as default.
@database (Single_Choice display=Display.Always values=[Option 'Nothing'])
set_database : Text -> Connection ! SQL_Error
set_database self database =
    if database == self.database then self else SQL_Error.throw_sql_error "Changing database is not supported."

In the new AST representation, this is all one Function node, with fields for all the types of line that contribute to a function definition.

Moving the assembly of full function definitions into the parser:

• Allows simplifying the GUI and backend logic (fixing some current GUI bugs)
• Allows the parser to catch errors when modifiers aren't able to be attached to an item

Merged PRs (4/5):

• Distinguish assignment/thunk by statement context #11324
  • Fixes GUI handling of 0-argument functions
• Replace private modifier node with field on supporting types #11346
  • Also introduce forward-compatible API for parser test cases
• Move TypeSignature into field of Function #11364
  • Parse tail of block as expression #11293
    • Fixes GUI handling of block with type-annotated tail.
  • Fixes GUI inserting a function "before" a function that has a type-sig line (i.e. when collapsing components).
• Move annotations into fields of Function and ConstructorDefinition #11374
  • Also enables multiline constructor definitions

Currently finishing last step:

• Move documentation into documented AST node #11302

Misc:

• Add the cloud file file browser to non cloud workflows #11139

Relevant backend changes:

• Metadata should not depend on absolute text spans Metadata should not depend on absolute text spans #11390

To discuss:
Two file edits on startup, which seem unnecessary.
