feat: added hooks for pyinstaller

[kumaraditya303]

For review instructions:

• Create a file main.py
• add this to the file

import os

from playwright.sync_api import sync_playwright

with sync_playwright() as p:
    browser = p.chromium.launch()
    page = browser.new_page()
    page.goto("http://whatsmyuseragent.org/")
    page.screenshot(path="example.png")
    browser.close()

• If you want to bundle browsers then set PLAYWRIGHT_BROWSERS_PATH=0 to include bowser's inside the binary and then download the browsers
• installer pyinstaller

pip install pyinstaller

• Run pyinstaller on the file like

pyinstaller -F main.py

• Binary would be placed in dist/ relative to current dir and test it

10+ individual users requested it, so makes sense to add support for it.

Fixes #513

LGTM, tested with the following test case:

1. PLAYWRIGHT_BROWSERS_PATH=0 playwright install chromium
2. pyinstaller -F test.py
3. clean browsers to make sure we are not using the wrong ones
4. PLAYWRIGHT_BROWSERS_PATH=0 ./dist/test

We can land if you somehow can set the env var for the driver automatically. Like detect somehow if its pyinstaller and then set it.

Had an offline discussion with him about it.
