✅ Simplify debugger API spec call sites

[watson]

Motivation

The debugger API specs often passed {} for placeholder this, args, or locals values. Those call sites were harder to read because it was not obvious which empty object represented which parameter.

Changes

• Added a shared thisArg test fixture for placeholder this values.
• Removed redundant trailing empty objects where onEntry, onReturn, and onThrow already provide default values.
• Left meaningful object literals in place when they are part of the test data or expectations.

Test instructions

• yarn test:unit --spec packages/browser-debugger/src/domain/api.spec.ts
