----------------------------
Description:
This is part of
[FLIP-556|https://cwiki.apache.org/confluence/display/FLINK/FLIP-556%3A+Introduce+BITMAP+Data+Type].
Add built-in scalar functions and BITMAP cast tests for the {{BITMAP}} type
introduced in FLINK-39185.
*Functions:*
* {{BITMAP_BUILD}} — create a bitmap from an integer array
* {{BITMAP_FROM_BYTES}} / {{BITMAP_TO_BYTES}} — serialize/deserialize bitmaps
* {{BITMAP_TO_ARRAY}} / {{BITMAP_TO_STRING}} — convert bitmaps to array/string
* {{BITMAP_CARDINALITY}} — get bitmap cardinality
* {{BITMAP_AND}} / {{BITMAP_ANDNOT}} / {{BITMAP_OR}} / {{BITMAP_XOR}} — bitmap
set operations
*Other:*
* Support {{BITMAP}} literal in Table API
* Add comprehensive {{BITMAP}} cast tests
* Add documentation (EN/ZH), Java Table API, and PyFlink bindings
