2024-07-23Simplify `CapabilitySet` Diagnostic Printing (#4678)ArielG-NV
Fixes: #4675 Fixes: #4683 Fixes: #4443 Fixes: #4585 Fixes: #4172 Made the following changes: 1. All capability diagnostic printing logic tries to simplify before printing. This means that we do not print atoms which imply another atom. 2. Do not print the `_` prefix part of atom names since it is misleading users on what they should use to solve a capability issue encountered. (`_Internal` `External` atom changes are not in this PR) 3. Bundle together printing of all sets which contain exactly the same atoms (excluding abstract atoms). This allows printing the following `vertex/fragment/hull/domain/... + glsl` instead of `vertex + glsl | fragment + glsl | hull + glsl | domain + glsl | ....` 4. Rework how entry-point errors are reported to users (example at bottom of PR comment) 5. Rework how atom-provenance data is collected to be leaner and more useful so we can rework the errors. There are 2 notable changes here: * We no longer store a list which describes where the first of an `CapabilityAtom` comes from. This heavily simplifies AST logic for the capability system. AST parsing of capabilities is much faster. The trade-off is faster AST parsing and correct AST node data for slower diagnostics if an error is found * atom-provenance data now stores a reference to an atom's use-site to provide information on **where** and **what** is wrong with user code versus only sharing **what** and not where.
