Bug 1905239 - Add new parameters to HostEnsureCanCompileStrings hook.…

… r=tschuster

Currently, we do this via isRuntimeCodeGenEnabled whose single argument
is equivalent to codeString in "Dynamic Code Brand Checks" spec [1]. We
extend this hook to accept new parameters from that spec and adjust
PerformEval and CreateDynamicFunction accordingly. We don't change the
behavior for PerformShadowRealmEval [2] and WASM, i.e. we keep dummy
parameters.
