fix compat mode when no framework

[smarq8]

In some situation when using 'native' platform then pio might treat some libraries as compatible even if lib_compat_mode=strict is used and it will then fail to compile arduino library under native platform.
As native does not contain any 'framework' then 'is_frameworks_compatible()' might treat library as compatible even if library.json says its for 'arduino' only for example
Untill now i used lib_ignore to overcome this issue but in long term its hassle to keep it updated

platformio.ini

[env:main_dev_SDL]
platform = native
; framework = none
; board = non
lib_compat_mode = strict ; do nothing in this case as is_frameworks_compatible() will be false positive when no framework defined

[env:main_dev]
platform = espressif32
framework = arduino
board = esp32dev

library.json

{
	"name": "spiDev",
	"frameworks": "arduino",
	"platforms": "*"
}

PS. im not very familiar with python but 'is_frameworks_compatible' look very strange with its 'frameworks=["arduino", "energia"]' especially compared to 'platforms=self._manifest.get("platforms")' for 'is_platforms_compatible'

    def is_frameworks_compatible(self, frameworks):
        return PackageCompatibility(frameworks=frameworks).is_compatible(
            PackageCompatibility(frameworks=["arduino", "energia"])
        )

    def is_platforms_compatible(self, platforms):
        return PackageCompatibility(platforms=platforms).is_compatible(
            PackageCompatibility(platforms=self._manifest.get("platforms"))
        )
