Motivation:

We received a report that thrift modules do not support java 9 modules.
When checking the specification, it seems like a identifier needs to start with a JavaLetter.
ref: https://docs.oracle.com/javase/specs/jls/se16/html/jls-7.html#jls-7.4

Unfortunately, our thrift modules contain a dot followed by a digit, which isn't a JavaLetter.
i.e. thrift0.9 where 9 isn't a digit.

I propose that for thrift modules, the last dot is omitted to avoid this issue.
i.e. thrift0.9 -> thrift09

Modifications:

• Introduced a automaticModuleNameOverride so that the override configuration can live inside each module
• automaticModuleName is now null if not configured, or a provider if configured. This change is necessary so that the actual value of automaticModuleName is not determined at configuration time, giving each module a chance to configure its own ext property.
• Each Jar task now configures Automatic-Module-Name at execution time as opposed to configuration time. This is also necessary so that each module can configure its own ext property prior to setting the name.
• Each thrift module now sets its own automaticModuleNameOverride

Result:

• Closes Invalid Automatic-Module-Name for armeria-thrift0.9 #6075
