[wasm] Support stepping into Wasm from Javascript We detect a stepping in Wasm from Javascript into Wasm then prepare the target function for debugging. The trick is redirect the target to interpreter and set a 'fake' breakpoint in the first instruction. Currently we don't need to clear this 'fake' breakpoint since it won't notify unless user intend to step in.

Tests stepping from javascript into wasm
Installing code and global variable.
Calling instantiate function.
Waiting for wasm scripts to be parsed.

[strings] Reclaim a bit in the hash field By replacing usage of the IsNotArrayIndex bit with IsNotIntegerIndex, we get back one bit that we can use to increase the number of hash bits stored. The price is that strings that represent array/integer indices beyond the cacheable range will have to be scanned more often, but these strings should be rare, and we expect that the additional hash bit is more worthwhile to have.

Remove fake wasm scripts from V8 backend Inspector will no longer report per-function wasm scripts or provide wasm disassembly. Locations in wasm are now consistently reported through the inspector API as lineNumber=0 columnNumber=byte offset in module.
