Y Ethan Guo c4bc2deea0 [HUDI-3936] Fix projection for a nested field as pre-combined key (#5379 )

This PR fixes the projection logic around a nested field which is used as the pre-combined key field. The fix is to only check and append the root level field for projection, i.e., "a", for a nested field "a.b.c" in the mandatory columns.

- Changes the logic to check and append the root level field for a required nested field in the mandatory columns in HoodieBaseRelation.appendMandatoryColumns

Description of the relationship between each module

This repo contains the code that integrate Hudi with Spark. The repo is split into the following modules

hudi-spark hudi-spark2 hudi-spark3 hudi-spark3.1.x hudi-spark2-common hudi-spark3-common hudi-spark-common

hudi-spark is the module that contains the code that both spark2 & spark3 version would share, also contains the antlr4 file that supports spark sql on spark 2.x version.
hudi-spark2 is the module that contains the code that compatible with spark 2.x versions.
hudi-spark3 is the module that contains the code that compatible with spark 3.2.0(and above) versions。
hudi-spark3.1.x is the module that contains the code that compatible with spark3.1.x and spark3.0.x version.
hudi-spark2-common is the module that contains the code that would be reused between spark2.x versions, right now the module has no class since hudi only supports spark 2.4.4 version, and it acts as the placeholder when packaging hudi-spark-bundle module.
hudi-spark3-common is the module that contains the code that would be reused between spark3.x versions.
hudi-spark-common is the module that contains the code that would be reused between spark2.x and spark3.x versions.
