Allow Bit-Shift by an uint

[BoyBaykiller]

Today operator '<<' and '>>' can not be applied if the left hand side is any integer type and the right hand side is uint:

public static uint Example(uint lhs, uint rhs)
{
    return lhs << rhs; // Operator '<<' cannot be applied to operands of type 'any integer type' and 'uint'
}

Users are required to cast from uint to int. I am advocating for lifting this artifical restriction to avoid uneccessary casts. Just like #9635.

uint is very popular when doing bitwise ops. Even more so in native code (relevant for porting to C#)
One real-word example from BitArray:

uint arrIndex = index / 8;
uint bitIndex = index % 8;
uint mask = (1 << (int)bitIndex); // uneccessary cast to int required
return (data[arrIndex] & mask) != 0;

index must be uint to get efficient codegen. When I create the mask I have to cast.

Should be doable with extension operators when C# 14 is released in a couple months.

Take a look:
