cmake: Set ENVIRONMENT property for examples on Windows 
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.

build: Introduce SECP256K1_STATIC macro for Windows users 
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.

77445898a5852ecd38ab95cfb329333a82673115 Remove `SECP256K1_INLINE` usage from examples (Hennadii Stepanov)

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

Pull request description:

  This PR adds a [CMake](https://cmake.org/)-based build system.

  Added build instructions and examples to the [`README.md`](https://github.com/hebasto/secp256k1/blob/220628-cmake/README.md#building-with-cmake-experimental) file.

  Ways to integrate with downstream CMake-based projects:
  - if `secp256k1` is a subtree (including Bitcoin Core project) -- `add_subdirectory(secp256k1)`
  - if `secp256k1` has been installed -- `find_package(secp256k1 0.2.1 CONFIG)`, see https://github.com/hebasto/secp256k1-CMake-example

  Added a few toolchain files for easy cross compiling.

  **Implementation notes**

  Minimum required CMake version is 3.1. This was required to provide [`C_STANDARD`](https://cmake.org/cmake/help/latest/prop_tgt/C_STANDARD.html) property.

  In turn, this choice of CMake version implies it is not possible to build with default CMake on Debian 8, which has CMake v3.0.2 only.

739c53b19a examples: Extend sig examples by call that uses static context 
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.
