[C API] Add bottom heap types and array heap type (#5150)

Adds `BinaryenHeapTypeNone`, `BinaryenHeapTypeNoext` and `BinaryenHeapTypeNofunc` to obtain the bottom heap types. Also adds `BinaryenHeapTypeIsBottom` to test whether a given heap type is a bottom type, and `BinaryenHeapTypeGetBottom` to obtain the respective bottom type given a heap type.
