[PATCH v6 5/6] oeqa/sdk/meson: improve test to validate host/build target assignments

[Tom Hochstein <tom.hochstein@oss.nxp.com>]

From: Ross Burton <ross.burton@arm.com>

Use 'meson introspect' to dump JSON describing the build configuration
and validate that the build and host architectures are correctly set in
the meson.cross file.

Also instead of calling ninja directly, call the relevant meson commands.

Fixes: [YOCTO #15485]
