[package] mpdecimal/2.5.1: Extra dependency on automake for MSVC builds

[StingX84]

Description

The package sets dependence on "Autoconf" and "Msys2" for MSVC, although only NMAKE is used during build.

The function that determines the dependence at the current moment:

    def build_requirements(self):
        if is_msvc(self):
            self.tool_requires("automake/1.16.5")
        else:
            # required to support windows as a build machine
            if self._settings_build.os == "Windows":
                self.win_bash = True
                if not self.conf.get("tools.microsoft.bash:path", check_type=str):
                    self.tool_requires("msys2/cci.latest")

But can be perfectly simplified to:

    def build_requirements(self):
        # required to support windows as a build machine
        if not is_msvc(self) and self._settings_build.os == "Windows":
            self.win_bash = True
            if not self.conf.get("tools.microsoft.bash:path", check_type=str):
                self.tool_requires("msys2/cci.latest")

With this configuration, everything builds without any problem and extra large dependencies.
