Add Spring Pulsar transaction support

Browse Source 
Adds auto-config for Spring for Apache Pulsar transactions.

Introduces a new `spring.pulsar.transaction.enabled` property
which can be used to enable transactions. This feature is
opt-in and remains disabled by default.

See gh-40189

== Transaction Support
Spring for Apache Pulsar supports transactions when using `PulsarTemplate` and `@PulsarListener`.
NOTE: Transactions are not currently supported when using the reactive variants.
Setting the configprop:spring.pulsar.transaction.enabled[] property to `true` will:
* Configure a `PulsarTransactionManager` bean
* Enable transaction support for `PulsarTemplate`
* Enable transaction support for `@PulsarListener` methods
The `transactional` attribute of `@PulsarListener` can be used to fine-tune when transactions should be used with listeners.
For more control of the Spring for Apache Pulsar transaction features you should define your own `PulsarTemplate` and/or `ConcurrentPulsarListenerContainerFactory` beans.
You can also define a `PulsarAwareTransactionManager` bean if the default auto-configured `PulsarTransactionManager` is not suitable.
