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.

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.

Currently the inspector reports Wasm in one of two ways:
- If there is a source map, report one script per Wasm script, with
bytecode but no source.
- If there is no source map, report one script per Wasm function, with
source (Wasm disassembly) but no bytecode.
With this change, behavior with source map is same, but without source
map it will report both ways. This will allow us to change the frontend
to do its own disassembly, allowing us to remove the per-function scripts
in a future change.

Currently, when debugging wasm, the internal script URL is shown, which
has the form wasm://wasm/wasm-<hex-script-id>. With this change, if the
module specifies a module name, it would report the URL as
wasm://wasm/<module-name>-<hex-script-id>, as this will help the user
identify what they are debugging.
