Catch additional deprecated methods in `no-deprecated-context-methods` rule

[bmish]

The no-deprecated-context-methods could catch additional methods:

• getAncestors() -> SourceCode#getAncestors(node)
• getDeclaredVariables() -> SourceCode#getDeclaredVariables(node)
• getScope() -> SourceCode#getScope(node)
• markVariableAsUsed(name) -> SourceCode#markVariableAsUsed(name, node)

There's also a property we could catch:

• parserServices -> SourceCode#parserServices

Note that there's a challenge of supporting both styles in order to support both ESLint v8 and v9, as in:

• feat: preparing for eslint v9 #400

I'm not sure if this is autofixable as a new node parameter needs to be captured and passed.

These deprecated members are being removed in ESLint v9:

• Change Request: Remove deprecated context pass-through SourceCode methods eslint/eslint#17520
• feat!: Remove deprecated context methods eslint/eslint#17698
