/**
Internal function that converts a decimal value to a Null-terminated string.
Converts the decimal number specified by Value to a Null-terminated
string specified by Buffer containing at most Width characters.
If Width is 0 then a width of MAXIMUM_VALUE_CHARACTERS is assumed.
The total number of characters placed in Buffer is returned.
If the conversion contains more than Width characters, then only the first
Width characters are returned, and the total number of characters
required to perform the conversion is returned.
Additional conversion parameters are specified in Flags.
The Flags bit LEFT_JUSTIFY is always ignored.
All conversions are left justified in Buffer.
If Width is 0, PREFIX_ZERO is ignored in Flags.
If COMMA_TYPE is set in Flags, then PREFIX_ZERO is ignored in Flags, and commas
are inserted every 3rd digit starting from the right.
If Value is < 0, then the fist character in Buffer is a '-'.
If PREFIX_ZERO is set in Flags and PREFIX_ZERO is not being ignored,
then Buffer is padded with '0' characters so the combination of the optional '-'
sign character, '0' characters, digit characters for Value, and the Null-terminator
add up to Width characters.
If Buffer is NULL, then ASSERT().
If unsupported bits are set in Flags, then ASSERT().
If Width >= MAXIMUM_VALUE_CHARACTERS, then ASSERT()
@param Buffer Pointer to the output buffer for the produced Null-terminated
string.
@param Flags The bitmask of flags that specify left justification, zero pad,

@param Value The 64-bit signed value to convert to a string.
