[compiler-rt][ARM] Optimized double precision FP add/sub (#179921)

The one new assembly source file, `arm/adddf3.S`, implements both
addition and subtraction via cross-branching after flipping signs, since
both operations must provide substantially the same logic. The new cmake
properties introduced in a prior commit are used to arrange that
including `adddf3.S` supersedes the C versions of both addition and
subtraction, and also informs the test suite that both functions are
available to test.

#ifdef ARM_NAN_HANDLING
// Tests specific to the NaN handling of Arm hardware, mimicked by
// arm/adddf3.S:
//
// - a quiet NaN is distinguished by the top mantissa bit being 1
//
// - if a signalling NaN appears in the input, the output quiet NaN is
// obtained by setting its top mantissa bit and leaving everything else
// unchanged
//
// - if both operands are signalling NaNs then the output NaN is derived
// from the first operand
//
// - if both operands are quiet NaNs then the output NaN is the first
// operand
//
// - invalid operations not involving an input NaN return the quiet
// NaN with fewest bits set, 0x7ff8000000000000.

// Tests specific to the NaN handling of Arm hardware, mimicked by
// the subtraction function in arm/adddf3.S:
//
// - a quiet NaN is distinguished by the top mantissa bit being 1
//
// - if a signalling NaN appears in the input, the output quiet NaN is
// obtained by setting its top mantissa bit and leaving everything else
// unchanged
//
// - if both operands are signalling NaNs then the output NaN is derived
// from the first operand
//
// - if both operands are quiet NaNs then the output NaN is the first
// operand
//
// - invalid operations not involving an input NaN return the quiet
// NaN with fewest bits set, 0x7ff8000000000000.
