  [llvm-mc] Default output assembly variant to AssemblerDialect (#186317)

Previously, llvm-mc always defaulted to output assembly variant 0
regardless of the target's AssemblerDialect. This was inconsistent:
llvm-mc -x86-asm-syntax=intel changed the input parser to Intel syntax
but output stayed AT&T, unlike clang's -masm=intel which affects both.

When --output-asm-variant is not explicitly specified, fall back to
MAI->getAssemblerDialect() instead of hardcoding variant 0. This
makes the output match the target's configured dialect:

- X86: -x86-asm-syntax=intel now produces Intel output
- AArch64: Apple triples default to Apple syntax output
- SystemZ: z/OS triples default to HLASM syntax output

Tests that relied on a specific output variant now use explicit
--output-asm-variant=0.
