Add ability to configure playwright in test file

[mmarkelov]

#216

Seems to be a bit challenging to implement this in a nice way. IDK if it will be helpful to configure playwright for just one test. The only founded solution was to use isolation playwright configuration.
It will be smth like that:

describe('Simple tests',  () => {
    beforeAll(async () => {
        await page.goto('https://google.com/')
    })

    test('test1', async () => {
        await jestPlaywright.config({
            browser: 'chromium',
            launchType: "LAUNCH",
            launchOptions: {
                headless: false,
                devtools: true,
            }
        }, async ({page}) => {
            // page is coming from function params
            await page.goto('https://github.com/')
            const title = await page.title()
            expect(title).toBe('Google')
        })
    })

    test('test2', async () => {
        const title = await page.title()
        expect(title).toBe('Google')
    })

    afterAll(async () => {
        await page.close()
    });
})

Also IDK the way of passing config. Should we merge jest-playwright config or we should use only config, passed throw jestPlaywright.config function
