Allow new integration setup on the instance with config options

[sl0thentr0py]

Description

Currently setup_once is called without any arguments so cannot access either the SDK init options or the integration specific init arguments on the instance. This PR enables a separate backwards compat optional setup_once_with_options as an instance method.

Note that we we will use this rarely but I need it to unblock the OTLPIntegration since I need the DSN there.

Example

before

sentry_sdk.init(dsn="")

class FooIntegration(Integration):
    def __init__(self, bar=42):
        self.bar = bar

    @staticmethod
    def setup_once():
        self.bar # Not available
        options.dsn  # Not available

after

    def setup_once_with_options(self, options=None):
        self.bar
        options.dsn

I don't love it but probably the least invasive way to go about things atm

Worth exploring migrating everything to the instance method at some point in the future
