On BLE builds where proto_varint_value_t is uint64_t, decode_zigzag32()
takes uint32_t — make the narrowing explicit to match the static_cast
pattern used for other type conversions in generated code.

Replace per-override #ifdef USE_API_VARINT64 conditionals with a
single type alias proto_varint_value_t, eliminating preprocessor
blocks from every decode_varint signature in api_pb2.cpp/h.

Pass uint32_t (or uint64_t when USE_API_VARINT64 is defined) directly
to decode_varint() instead of the ProtoVarIntResult struct. This
eliminates accessor method overhead in each of the 51 overrides,
replacing value.as_uint32() with direct value usage, value.as_bool()
with value != 0, etc. No vtable growth - single virtual method with
conditionally-typed parameter.

Replace optional<ProtoVarInt> + consumed pointer with ProtoVarIntResult
struct that returns value + consumed count directly. This eliminates
memory stores through a pointer on the fast path (single-byte varints
< 128), keeping everything in registers.
The parse() method is now ESPHOME_ALWAYS_INLINE with the multi-byte
slow path outlined to parse_slow_(). The common case for protobuf
field tags, small enums, booleans, and typical message sizes/types
is a simple high-bit check + register return with no function call.
Measured on ESP32 (Xtensa): try_read_frame_ grows only +12 bytes
(320 → 332) for two inlined parse sites, while eliminating two
function calls per message on the hot path.
