In K2 mode the frontend emits `-123L` as IrCall(unaryMinus, IrConst(123L))
rather than IrConst(-123L) as in K1. Queries that search for negative numeric
literals therefore need to match both a UnaryMinusExpr wrapping a literal and a
plain literal, depending on language mode.
Fix: when extractCallExpression encounters an isNumericFunction(unaryMinus) call
whose dispatchReceiver is already an IrConst, fold the negation into the constant
before extracting. The resulting literal node is identical to what K1 emits.
Location: extend the span one character to the left to cover the `-` sign.
In K2 the IrCall's startOffset equals the receiver's startOffset, so we recover
the minus by subtracting one from the receiver offset.
K1 is unaffected: the K1 frontend folds the sign into the constant before IR
generation, so this new branch never triggers when compiling with -language 1.9.
Expected output changes:
- test-kotlin2/library-tests/literals/literals.expected: negative long, float and
double literals now appear as plain typed literals instead of as UnaryMinus nodes.
The file is now byte-identical to test-kotlin1/library-tests/literals/literals.expected.

* Update documentation to only claim support for 2.4.0x
* Python test code; remove newlines between imports.
* Sync comments between kotlin 1.8 and 1.9
* Update code comments to attach where actually relevant,
and improve comments on IrMemberAccessExpression<*>.extensionReceiverParameterIndex()
Add the Kotlin 2.4.0 compiler plugin variant (component registrar,
IR compatibility shims, and version-specific utilities), bundle the
2.4.0 compiler dependencies, and update the build wiring, supported
version metadata and the too-new diagnostic bound.

Accept test changes from Kotlin 2.3.0 update
Updates expected test outputs for kotlin2 library tests to match
actual compiler output. Changes include:
- Location adjustments for properties/methods (now point to identifiers)
- CastExpr -> ImplicitCastExpr for implicit type casts
- Removed duplicate BlockStmt entries in loop ASTs
- Super constructor call location changes
Note that in Kotlin 2.3.0 super constructor calls now have locations spanning
entire class declarations instead of the actual super call site.
This change rolls up all files from v1_6_0, v1_6_20, v1_7_0 and v_1_7_20.
In addition, versioned files that are not overridden by any later Kotlin versions (i.e. files that only have one copy under utils/versions) are inlined and removed to simplify list of changes.

Previously, we were using 8.0.0rc1.
In particular, this upgrade means we need to explicitly
import more rules, as they've been moved out of the core bazel repo.
This matches the Java extractor's treatment of these literals, and so enables dataflow type-tracking to avoid special-casing Kotlin. Natively, Kotlin would regard this as kotlin.Nothing?, the type that can only contain null (kotlin.Nothing without a ? can take nothing at all), which gets Java-ified as java.lang.Void, and this will continue to be used when a null type has to be "boxed", as in representing substituted generic constraints with no possible type.
