7f2bda1066 Rust: Add full upgrade script for dbscheme migration
Adds upgrade.ql with transformations for all schema changes from
rust-analyzer 0.0.301 to 0.0.328:
- Meta split into PathMeta/KeyValueMeta/TokenTreeMeta/UnsafeMeta
- TraitAlias merged into Trait
- BlockExpr.isTry() -> TryBlockModifier
- StructField.getDefault() -> getDefaultVal() returning ConstArg
- Variant.getDiscriminant() -> getConstArg() returning ConstArg
- FormatArgsArg.getName() -> getArgName() returning FormatArgsArgName

ac27c20711 Rust: fix consistency test failures from rust-analyzer upgrade
- Exclude macro-expanded and attribute paths from PathResolutionConsistency
  (tokio::main and similar attribute macros resolve to multiple proc macro fns)
- Exclude "macro expansion failed" warnings from ExtractionConsistency
  (compile_error! and undefined macros are expected to fail expansion)
- Update pre-existing consistency expectations (net multipleResolvedTargets)
- Update type-inference.expected for new RA results

87a0ed190f Rust: fix LoadCargoConfig defaults (proc_macro_processes must be >= 1)
Setting proc_macro_processes to 0 causes an index-out-of-bounds panic
in ProcMacroServerPool::new when the proc macro server is enabled.
Use the same defaults as rust-analyzer itself (1 each).

68ab2fb738 Rust: fix QL references for schema changes and add upgrade/downgrade scripts
- Fix Meta usage: Meta is now abstract with subtypes (PathMeta, KeyValueMeta, TokenTreeMeta, etc.)
- Fix FormatArgsArg: getName() replaced by getArgName() returning FormatArgsArgName
- Add upgrade script (old → new) and downgrade script (new → old)
- Update Definitions.qll, PathResolution.qll, BadCtorInitialization.ql, FormatTemplateVariableAccessConstructor.qll
