This change simplifies running examples on Windows, because the DLL
must reside either in the same folder where the executable is or
somewhere in PATH.

It is a non-Libtool-specific way to explicitly specify the user's
intention to consume a static `libseck256k1`.
This change allows to get rid of MSVC linker warnings LNK4217 and
LNK4286. Also, it makes possible to merge the `SECP256K1_API` and
`SECP256K1_API_VAR` into one.
An executable target in the `COMMAND` option will automatically be
replaced by the location of the executable created at build time.
This change fixes tests for Windows binaries using Wine.

Pull request description:
From [IRC](https://gnusha.org/secp256k1/2023-01-31.log):
> 06:29 \< hebasto\> What are reasons to define the `SECP256K1_INLINE` macro in user's `include/secp256k1.h` header, while it is used internally only?
> 06:32 \< hebasto\> I mean, any other (or a new dedicated) header in `src` looks more appropriate, no?
> 06:35 \< sipa\> I think it may just predate any "utility" internal headers.
> 06:42 \< sipa\> I think it makes sense to move it to util.h
Pros:
- it is a step in direction to better organized headers (in context of #924, #1039)
Cons:
- code duplication for `SECP256K1_GNUC_PREREQ` macro

Besides improving the examples, this makes sure that the examples
import a variable (instead of a function), namely the static context,
from the library. This is helpful when testing MSVC builds, because
the MSVC linker tends to be awkward when importing variables.
