[FIR] KT-57104: Preserve @JvmName on fake-override accessors

Otherwise, when we come to `ClassCodegen.kt:173
for `GradleActionTest` and check
`FUN FAKE_OVERRIDE name:<get-project>`,
we then go to `JvmSignatureClashDetector.kt:37`,
and call `mapRawSignature(overriddenFunction)`
which ignores the original `@JvmName`.
It does so because it relies on the property copy
which forgets to copy the getter, but
`@get:JvmName` is stored in it.

Extra when-branches for `FAKE_OVERRIDE` are needed,
because otherwise the annotations would not
be copied in `Fir2IrDeclarationStorage.kt:723`.

Extra when-branches for `DELEGATED_MEMBER` are
needed, because otherwise the generated IR changes
in some tests. For example, see:
`FirLightTreeIrTextTestGenerated.Declarations.testKt35550`.

The `assumesBackingField`-related change is backed by
the `FirLightTreeIrTextTestGenerated.Stubs.testJavaEnum` test.

`this.body = null` ensures the resulting IR
matches K1.

The change in `FirImplicitBodyResolve.kt` is needed,
because otherwise the bootstrap compiler fails at
`:compiler:frontend:compileKotlin`,
but I didn't come up with a smaller test for it.

If we don't make an explicit accessor copy,
then when we later create a `Fir2IrLazyPropertyAccessor`
for the fake override getter, it's `fir` will
be a reference to the `FirProperty`, not `FirPropertyAccessor`.
That's why `DumpIrTreeVisitor` will render `IntrinsicConstEvaluation` as
a getter annotation as well.

`FirPsiIrTextTestGenerated.testDelegatedGenericImplementation`
renders type parameters from `<get-x>`,
because when assigning `extensionReceiverParameter`
of the setter `<set-x>` we come to
`Fir2IrClassifierStorage.kt:638`,
and in this cache there's the parameter with
the `<get-x>` parent.
Note that `typeContext.origin == DEFAULT` in
`getCachedIrTypeParameter`.
It's `DEFAULT` because at the line `Fir2IrDeclarationStorage.kt:335`
the `function` variable is `null` (because there's no setter).

The change in `declarationAttributes.kt` is backed
by the `FirPsiIrTextTestGenerated.testKt45853` test.
