  [Clang][AArch64] Include SME attributes in the name mangling of function types (#114209)

Similar to arm_sve_vector_bits, the mangling of function types is
implemented as a pseudo template if there are any SME attributes
present, i.e.

  `__SME_ATTRS<normal_function_type, sme_state>`

For example, the following function:

  `void f(svint8_t (*fn)() __arm_streaming) { fn(); }`

would be mangled as:

  `_Z1fP11__SME_ATTRSIFu10__SVInt8_tELj1EE`
