Allow BOM module to be inferred from setting key

[vrozov]

Support use case like:

lazy val bomModuleID = settingKey[ModuleID]("bom module ID")
bomModuleID:= ModuleID(organization, name, version)
lazy val bom = Bom.dependencies(bomModuleID)

when, for example, version may not be hardcoded into the SBT build and is obtained from pom file like in apache/spark#52760 (comment)

@vrozov thank you for you contribution! Please run scala formatting as it is failing for your MR.

@vrozov I am ready to approve and merge the MR as soon the CI is green. The code looks good.

@dmitriy-abramov Thank you! Will it be possible to publish a new version of the plugin with the fix?
