[MC] Simplify MCBinaryExpr/MCUnaryExpr printing by reducing parentheses (#133674)
The existing pretty printer generates excessive parentheses for
MCBinaryExpr expressions. This update removes unnecessary parentheses
of MCBinaryExpr with +/- operators and MCUnaryExpr.
Since relocatable expressions only use + and -, this change improves
readability in most cases.
Examples:
- (SymA - SymB) + C now prints as SymA - SymB + C.
This updates the output of -fexperimental-relative-c++-abi-vtables for
AArch64 and x86 to `.long _ZN1B3fooEv@PLT-_ZTV1B-8`
- expr + (MCTargetExpr) now prints as expr + MCTargetExpr, with this
change primarily affecting AMDGPUMCExpr.
