EPA: Extend StringLiteral range to include trailing commas

This goes slightly against the exact printing philosophy where
trailing decorations should be in an annotation, but the
practicalities of adding it to the WarningTxt environment, and the
problems caused by deviating do not make a more principles approach
worthwhile.

Use symbol cache in internal interpreter too

This commit makes the symbol cache that was used by the external
interpreter available for the internal interpreter too.

This follows from the analysis in #23415 that suggests the internal
interpreter could benefit from this cache too, and that there is no good
reason not to have the cache for it too. It also makes it a bit more
uniform to have the symbol cache range over both the internal and
external interpreter.

This commit also refactors the cache into a function which is used by
both `lookupSymbol` and also by `lookupSymbolInDLL`, extending the
caching logic to `lookupSymbolInDLL` too.
