Move Eigen::all,last,lastp1,lastN to Eigen::placeholders::.
...
These names are so common, IMO they should not exist directly in the
`Eigen::` namespace. This prevents us from using the `last` or `all`
names for any parameters or local variables, otherwise spitting out
warnings about shadowing or hiding the global values. Many external
projects (and our own examples) also heavily use
```
using namespace Eigen;
```
which means these conflict with external libraries as well, e.g.
`std::fill(first,last,value)`.
It seems originally these were placed in a separate namespace
`Eigen::placeholders`, which has since been deprecated. I propose
to un-deprecate this, and restore the original locations.
These symbols are also imported into `Eigen::indexing`, which
additionally imports `fix` and `seq`. An alternative is to remove the
`placeholders` namespace and stick with `indexing`.
NOTE: this is an API-breaking change.
Fixes #2321 .

Introduce a variable_or_fixed<N> proxy returned by fix<N>(val) to pass both a compile-time and runtime fallback value in case N means "runtime".
...
This mechanism is used by the seq/seqN functions. The proxy object is immediately converted to pure compile-time (as fix<N>) or pure runtime (i.e., an Index) to avoid redundant template instantiations.
