Previously we keep a separate static grammar table for opcodes/ operands per SPIR-V version. This commit changes that to use a single unified static grammar table for opcodes/operands. This essentially changes how grammar facts are queried against a certain target environment. There are only limited filtering according to the desired target environment; a symbol is considered as available as long as: 1. The target environment satisfies the minimal requirement of the symbol; or 2. There is at least one extension enabling this symbol. Note that the second rule assumes the extension enabling the symbol is indeed requested in the SPIR-V code; checking that should be the validator's work. Also fixed a few grammar related issues: * Rounding mode capability requirements are moved to client APIs. * Reserved symbols not available in any extension is no longer recognized by assembler.
