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
