  [compiler-rt][ARM] Optimized integer -> FP conversions (#179928)

This commit adds a total of 8 new functions, all converting an integer
to a floating-point number, varying in 3 independent choices:

* input integer size (32-bit or 64-bit)
* input integer type (signed or unsigned)
* output float format (32-bit or 64-bit)

The two conversions of 64-bit integer to 32-bit float live in the same
source file, to save code size, since that conversion is one of the more
complicated ones and the two functions can share most of their code,
with only a few instructions differing at the start to handle negative
numbers (or not).
