[evasgl] reduce shader list for performance

In most cases, application use a few shaders.
for booting performance, evas need to reduce shader in precompile time.
even if application need new shader, they will be compiled and saved in runtime.
because they will be saved shared file, other appication need not compile shader if it is already compiled by other app.
