[code-reflection] RFR: Skip constant conditional branch transformation.

[Adam Sotona]

Lowering of pattern matching in switch statements and expressions produces an inefficient tree of conditional branches. This PR does not improve the lowering itself; however, it reduces overhead in the generated bytecode. 
The `BytecodeGenerator` prepends `SKIP_CBRANCH_TRANSFORM`, a proprietary transformation focused on redundant conditional branches. It skips intermediate conditional branches with constant boolean arguments and re-targets them directly to the true or false branch, based on the argument's constant value.
