This function is duplicate to nDims(): https://github.com/apache/sedona/blob/master/common/src/main/java/org/apache/sedona/common/Functions.java#L298
Please copy the logic of nDims here and let nDims function call this getDimension function.

Good idea.
I added SRID in them.

[SEDONA-XXX] my subject.What changes were proposed in this PR?
GetDimension will support 2D and 3D, which will lead functions like ST_AsWKT ignore the M coordinate. After this PR is merged, M coordinate will be available in WKT format.
In short, current status of Sedona Input and Output ST functions are follows:
Sedona Jvm serializer will carry XYZM + SRID. So any ST functions in Sedona can access XYZM in the geometry type.
Shapely serializer does not support M so when deal with data created by Shapely, M is ignored.
How was this patch tested?
Comprehensive unit tests in sedona-common
