spirv: Generalize OpSelect

SPIR-V 1.4 supports OpSelect over any composite type, and also allows
scalar boolean condition for vector types -- a case which we already
handled to support old GLSLang.

Added a helper function to recursively perform nir_bcsel, that makes
easier to support structs.

v2: Replace asserts() with vtn_fail_if().  (Jason)

v3: Simplify Condition and Result types verifications.  (Jason)
