[AndroidCrypto] Fix remaining Algorithms test failures.

[jkoritzinsky]

Product fixes:

• Return a different error code for curve-not-supported to correctly throw PNSE.

Test fixes:

• Allow platforms that support explicit curves to indicate they support a particular curve when parameters are supplied explicitly but not by name
• Split the DSA tests by key size for easy disabling on Android.
• Disable a few tests that won't pass on Android (some of which are disabled on other platforms).
