[Runtime][Build] Enable freestanding builds for IREE_PLATFORM_GENERIC (#24820)

Avoid assuming POSIX facilities are available on Generic platforms,
allowing the runtime to build for freestanding/bare-metal targets.

This disables POSIX-dependent functionality such as sockets and singal
handling by default, avoids selecting a POSIX async proactor, and
provides the small platform fallbacks needed by the Generic runtime
build.

This commit also adds Bazel support for the Generic riscv64
configuration, which is currently being brought up. It fixes additional
build-system issues encountered during Generic riscv bring up.

IREE: Intermediate Representation Execution Environment

IREE (Intermediate Representation Execution Environment, pronounced as “eerie”) is an MLIR-based end-to-end compiler and runtime that lowers Machine Learning (ML) models to a unified IR that scales up to meet the needs of the datacenter and down to satisfy the constraints and special considerations of mobile and edge deployments.

See our website for project details, user guides, and instructions on building from source.
