gdbarch: Use an anonymous union for target data in `gdbarch_info'

As an update to commit ede5f15146ae ("gdbarch.h: Change
gdbarch_info::tdep_info's type to void *") replace the definition of the
`tdep_info' member in `struct gdbarch_info' with an anonymous union,
comprising the original member, with its type reverted to `struct
gdbarch_tdep_info *', a `tdesc_data' member of a `struct tdesc_arch_data
*' type and an `id' member of an `int *' type.  Remove now unnecessary
casts throughout use places then, making code easier to read an less
prone to errors, which may happen with casting.

	a union of `tdep_info', `tdesc_data' and `id'.
