[PATCH v2 09/19] target/riscv: remove cpu->cfg.ext_e

[Daniel Henrique Barboza]

Create a new "e" RISCVCPUMisaExtConfig property that will update
env->misa_ext* with RVE. Instances of cpu->cfg.ext_e and similar are
replaced with riscv_has_ext(env, RVE).

Remove the old "e" property and 'ext_e' from RISCVCPUConfig.
