Parse and use `send-default-pii` and `max-request-body-size` from `sentry.properties`

[adinauer]

:scroll: Description

We now parse and use send-default-pii and max-request-body-size from sentry.properties.

• max-request-body-size was already being parsed but never applied to SentryOptions
• send-default-pii was neither parsed nor applied

:bulb: Motivation and Context

As of 8.0.0-alpha.2 our Sentry OpenTelemetry Java Agent has been released and is supposed to be a vital part in our future Performance instrumentation. Some features (e.g. error reporting) are currently still based on the integrations that existed before.

Some data is only sent when certain options are enabled (see PR title). We never parsed those until now, meaning our OpenTelemetry Agent Init wasn't able to utilize all of the functionality Sentry offers.

NOTE: There might be more options, that aren't parsed yet. We should investigate and fix. Here's an issue for that: https://github.com/getsentry/sentry-java/issues/3535

:green_heart: How did you test it?
