Add actions to just run make and test

[take-cheeze]

• Tested on Add actions to just run make and test take-cheeze/mquickjs#1
• Adding -Wno-error=unused-result flag for result of fread

[bellard]

OK for the actions but without the Makefile change (it is no longer required as -Werror was removed).

@bellard Thank you for reviewing. I've resolved the conflict and removed Makefile change

Without asan? Or at least valgrind

[bellard]

It would be interesting to add other tests such as:

• "make test" in 32 bit (CONFIG_X86_32=y)
• "make test" with mac OS build
• "make test" with ASAN
• ARM 32 bit "make test" using either cross tools (arm-linux-gcc + qemu to run make test) or in an ARM distribution (as in the QuickJS CI).

Yeah, having more test environment seems to be interesting.
Though it will need many changes to Makefile and I'd like to have a base line CI first and add other cases later.
