The clamp function was defined in Base.Math, but required to be in Base now, so move it to intfuncs with other similar functions

Fixes #55279

This is a more apt description, since it is not floating point related,
and used earlier (such as in IOBuffer).

Fixes #55279
This fits into a 32-byte allocation pool, saving up to 64 bytes when
repeatedly reading small chunks of data (e.g. tokenizing a CSV file). In
some local `@btime` measurements, this seems to take <10% more time
across a range of output lengths.

The `clamp` function was defined in Base.Math, but required to be in
Base now, so move it to intfuncs with other similar functions
