What happened?

Adding a LocatorStrategy on a multi-remote browser throws scope.strategies.get is not a function. It sounds like this is not supported. Moreover, not sure how this should behave, or if it should just not exist...

What is your expected behavior?

Either it does not crash, or addLocatorStrategy is not on the interface since it is not a thing

How to reproduce the bug.

                it('should addLocatorStrategy on multi-remote', async () => {
                    multiRemoteBrowser.addLocatorStrategy('selectHeader', (selector: any) => document.querySelector(selector) as HTMLElement)
                })

Potential Fix

The below changes around https://github.com/dprevost-LMI/webdriverio/blob/5a12a5e5b341cda14d3076f8f48a19da7f8f8a83/packages/webdriverio/src/multiremote.ts#L78, fixes the issue but the question is more: how should locator strategy behavior on multi-remote before fixing this issue

        // Fixes `Cannot read properties of undefined (reading 'get')`
        const strategies = wrapperClient.__propertiesObject__.strategies?.value
        propertiesObject.strategies = {
            value: strategies instanceof Map ? strategies : new Map()
        }

        for (const commandName of wrapperClient.commandList) {
            // Fixes `scope.strategies.get is not a function`
            if (typeof wrapperClient[commandName] !== 'function') {
                continue
            }

            propertiesObject[commandName] = {
                value: this.commandWrapper(commandName),
                configurable: true
            }
        }

Start in packages/webdriverio/src/multiremote.ts around line 78 and reproduce the failure from the multiRemoteTest.e2e.ts case at line 322. Determine the intended multi-remote behavior for addLocatorStrategy, then add regression coverage showing that behavior and verify the scope.strategies error no longer occurs.
