This replaces the previous CheckStringAdd operator which deopts in case the combined length overflows with a dedicated pure StringConcat operator. This operator is similar to NewConsString in that it takes the resulting length plus the two input strings. The operator relies on the length being checked explicitly by the surrounding code instead of baking the check into the operator itself. This way TurboFan can eliminate redundant/unnecessary StringConcat operations, since they are pure now. This also unifies the treatment of string addition in JSTypedLowering, and generalizes the StringLength constant-folding to apply to more cases not just the JSAdd cases inside JSTypedLowering.

This optimization addresses a case triggered by the Templates/Untagged js-perf-test, in which template literals get compiled to a cascade of JSAdd(JSAdd, JSToString) nodes. Before the optimization in https://chromium-review.googlesource.com/c/v8/v8/+/1193342 JSToString no-ops used to get optimized away during typed lowering together with constant folding of string concatenation. This change allows us to get rid of a no-op JSToString call during native context specialization, thus allowing for constant folding of JSAdd to kick in and CheckStringAdd nodes to not be generated at all. This change also removes the NumberToString optimization from typed lowering, as it's being executed during earlier stage.

Adds support for zone allocated (off-heap) ConsumedPreParsingScopeData to enable worker-thread access to PreParsingScopeData during parallel IIFE compile tasks. In order to avoid code-duplication, a templated BaseConsumedPreParsingScopeData is added which implements the logic for decoding the bytestream into scope data. Two implementations of this base class are instantiated for each of the underlying serialized scope date: - ZoneConsumedPreParsedScopeData for exposing ZonePreParsedScopeData - OnHeapConsumedPreParsedScopeData for exposing on-heap PreParsedScopeData The interface for each of these classes is the ConsumedPreParsingScopeData, which exposes the methods required by the parser to deserialize the required data. As a side-cleanup, moved Ucs2CharLength and Utf8LengthHelper implementations to cc file so that we don't get a linker error if one of them are unused by the cc file including the header.

Previously all internal accesses to the String::length field in TurboFan would use the StringLength operator, whereas explicit `string.length` accesses from user JavaScript code would use LoadField operators instead. This inconsistency led to redundant loads of the String::length, for example in case of code like ```js subject.substring(1, subject.length - 1) ``` where the `subject.substring` call introduces a StringLength(subject) node, and the `subject.length` introduces a LoadField[length](subject) node. Consistently using StringLength operator everywhere enables optimizations in TurboFan that had been blocked before here (besides avoiding the redundant load operations).
